Which Tyre is Best, HT or AT: A Comprehensive Guide to Choosing the Right Tires for Your Vehicle
Deciphering the HT vs. AT Tyre Dilemma: Which is the Right Fit for You?
For years, I’ve found myself staring at tyre shop windows, a familiar sense of bewilderment washing over me. The sheer variety of tyre options can be downright overwhelming, and nowhere is this more evident than when trying to decide between HT and AT tyres. It’s a question I’ve grappled with countless times, especially when my trusty SUV needed new shoes. Do I stick with the smooth, quiet ride of Highway Terrain (HT) tyres, or do I venture into the more rugged territory of All-Terrain (AT) tyres? This isn't just a cosmetic choice; it's a decision that profoundly impacts your vehicle's performance, safety, and even your fuel economy. Let's dive deep and unpack which tyre is best, HT or AT, to help you make an informed choice that truly suits your driving needs.
The Short Answer: Which Tyre is Best, HT or AT?
Generally, if you primarily drive on paved roads and prioritize a quiet, comfortable ride with optimal fuel efficiency, HT (Highway Terrain) tyres are likely the best choice. If you frequently venture off-road, tackle unpaved surfaces, or desire a more robust tyre for occasional light trails, AT (All-Terrain) tyres will generally serve you better, though with some trade-offs in on-road comfort and fuel economy. The "best" tyre is entirely subjective and depends on your individual driving habits, the types of roads you frequent, and your vehicle's intended use.
This isn't a simple one-size-fits-all answer, and that's precisely why understanding the nuances between HT and AT tyres is so crucial. I’ve seen friends regret their choices – one opting for ATs and complaining about the constant road noise on their daily commute, another sticking with HTs only to find themselves sliding precariously on a gravel road during a weekend getaway. The key takeaway is that each tyre type is engineered with specific purposes in mind, and choosing the wrong one can lead to a less-than-ideal driving experience.
Understanding the Fundamentals: What Exactly are HT and AT Tyres?
Before we can definitively answer "which tyre is best, HT or AT," we need a solid understanding of what each type entails. Tyre manufacturers design these categories to cater to different driving environments and demands.
Highway Terrain (HT) Tyres: The Pavement Specialists
HT tyres, as the name suggests, are engineered for the vast majority of driving: paved roads, highways, and urban environments. They are designed to provide a smooth, comfortable, and quiet ride, prioritizing longevity and fuel efficiency on surfaces that are generally consistent and predictable. Think of them as the workhorses for your daily commute, road trips, and city driving.
Key Characteristics of HT Tyres:
- Tread Design: HT tyres typically feature a more symmetrical and continuous tread pattern with smaller, tightly spaced blocks. This design minimizes road noise and maximizes the contact patch with the pavement, leading to excellent grip on dry and wet asphalt. The shallow tread depth also contributes to lower rolling resistance.
- Compound: The rubber compound used in HT tyres is generally harder, designed to wear slowly on abrasive asphalt surfaces. This contributes to their long lifespan.
- Construction: They are built with a focus on stability and responsiveness for on-road handling. The sidewalls are usually less reinforced than AT tyres, as they aren’t intended for significant impacts or flexing on rough terrain.
- Performance Focus: Primarily, HT tyres aim to deliver:
- Comfort: A smooth and quiet ride, absorbing road imperfections effectively.
- Fuel Efficiency: Lower rolling resistance means your engine doesn't have to work as hard, leading to better gas mileage.
- Longevity: Designed to last many miles on paved surfaces.
- On-Road Grip: Excellent traction on dry and wet pavement.
From my own experience, fitting a set of fresh HT tyres to my sedan transformed its demeanor. The previously noticeable road hum virtually disappeared, and the car felt more planted and responsive on curves. It was like giving the car a quiet hug for every mile driven on the highway.
All-Terrain (AT) Tyres: The Versatile Explorers
AT tyres are a hybrid, designed to offer a competent performance both on and off the paved road. They aim to strike a balance between the comfort and efficiency of HT tyres and the ruggedness required for light off-road adventures. If your driving involves a mix of highways, gravel roads, dirt paths, and perhaps occasional light trails, AT tyres are often the go-to choice.
Key Characteristics of AT Tyres:
- Tread Design: AT tyres boast a more aggressive, open tread pattern with larger, more widely spaced tread blocks. This design provides better grip on loose surfaces like dirt, mud, and gravel by allowing the tyre to bite into the material. The voids between the blocks help to eject mud and debris, preventing the tyre from getting clogged.
- Compound: The rubber compound is often a bit softer and more resilient than HT tyres, offering better traction on varied surfaces and increased resistance to punctures from rocks and debris.
- Construction: AT tyres are typically built with stronger sidewalls and more robust construction to withstand the rigors of off-road use, including impacts and flexing. This added durability is a significant advantage when venturing beyond smooth pavement.
- Performance Focus: AT tyres aim to provide a good compromise for:
- Off-Road Traction: Superior grip on dirt, gravel, mud, and other unpaved surfaces.
- Durability: Enhanced resistance to punctures and sidewall damage.
- On-Road Capability: Still offer decent performance on pavement, though not as refined as HT tyres.
- Towing and Hauling: Their robust construction can sometimes offer better stability when carrying heavy loads.
I remember when I first put a set of ATs on my pickup truck. The change was immediate. While the road noise increased noticeably, the confidence I felt on a recent camping trip, navigating a rutted dirt track, was well worth it. It felt like the truck was ready for anything, a sentiment HT tyres simply couldn't provide in that scenario.
Head-to-Head Comparison: HT vs. AT Tyres
Now that we understand the individual characteristics, let's directly compare them to help you decide which tyre is best, HT or AT, for your specific needs.
On-Road Performance: Comfort, Noise, and Handling
When it comes to the daily grind on paved roads, HT tyres generally reign supreme. Their design prioritizes a quiet, smooth ride. The continuous tread blocks and smaller sipes (grooves) create a larger contact patch with the road, minimizing the thumping and humming that can accompany more aggressive treads. This translates to a more pleasant and less fatiguing driving experience, especially on long journeys.
AT tyres, with their larger, more aggressive tread blocks, inevitably create more noise. You'll likely hear a discernible hum or roar from the road, particularly at highway speeds. While modern AT tyres have made significant strides in reducing this noise, they will almost always be louder than their HT counterparts. The wider spacing between tread blocks, while beneficial off-road, also means less consistent contact with the pavement, which can sometimes lead to slightly less precise handling on smooth surfaces, especially during sharp maneuvers.
My take: If your daily commute is 90% highway or city streets, the comfort and quiet of HT tyres are hard to beat. I’ve driven vehicles with both, and the difference in cabin noise is stark. For those sensitive to road noise or who spend hours on the highway, HT is the clear winner for on-road comfort.
Off-Road Capability: Traction and Durability
This is where AT tyres truly shine. Their aggressive tread patterns are designed to dig into loose surfaces like dirt, mud, sand, and gravel, providing superior traction where HT tyres would struggle. The open voids in the tread help to clear mud and debris, preventing the tyre from becoming a slick, useless disc. The reinforced construction and tougher sidewalls also offer better protection against punctures from sharp rocks, roots, and other trail hazards.
HT tyres, with their smooth, closely packed tread, offer very limited off-road performance. On dry, hard-packed dirt, they might be adequate, but as soon as you encounter loose gravel, mud, or sand, their limitations become painfully apparent. They lack the "bite" needed to grip these surfaces, and their less robust construction makes them more susceptible to damage.
My take: If you anticipate even occasional excursions onto unpaved roads – think dirt driveways, gravel access roads, or light trails – AT tyres offer a significant advantage in capability and peace of mind. I've seen friends get stuck with HT tyres on surfaces that my AT-equipped truck handled with ease. It's about having the right tool for the job, and off-road, ATs are that tool.
Fuel Efficiency: The Economic Factor
Fuel economy is a significant consideration for many drivers, and here, HT tyres generally have an edge. Their design features lower rolling resistance. This means less energy is required from your engine to keep the tyres rotating. The smoother tread pattern and harder rubber compound contribute to this efficiency. For a vehicle driven predominantly on highways, the cumulative effect of better fuel economy can translate into substantial savings over the lifespan of the tyres.
AT tyres, due to their more aggressive tread, larger void areas, and often softer rubber compounds, tend to have higher rolling resistance. This means your engine has to work harder to maintain speed, leading to a noticeable decrease in fuel efficiency. This reduction can range from a few percentage points to a more significant impact, depending on the specific AT tyre and your driving style.
My take: If maximizing your miles per gallon is a top priority, and your driving is almost exclusively on pavement, HT tyres are the economically sensible choice. The difference can add up quickly, especially with today's fuel prices. However, if you need the off-road capability, the slight dip in MPG might be a price you're willing to pay for versatility.
Tread Life and Durability
The longevity of a tyre is another critical factor. HT tyres are typically designed with harder rubber compounds that are optimized for wear on abrasive asphalt. This means they can often last for tens of thousands of miles under normal driving conditions. Their tread patterns are also designed to wear more evenly on smooth surfaces.
AT tyres, while built for durability in a more demanding environment, can sometimes have a shorter tread life on pavement compared to HT tyres. The softer compounds that offer better off-road grip can wear down faster on abrasive asphalt. However, the trade-off is their superior resistance to punctures and cuts from off-road debris, which can prematurely end the life of an HT tyre. The "durability" of AT tyres is therefore often measured differently – they might wear faster on pavement but are less likely to be rendered useless by a single puncture off-road.
My take: For pure pavement longevity, HT tyres are often the winners. But if you're frequently on gravel or trails, the puncture resistance of ATs can mean they actually last longer in *real-world* conditions for your specific use case. It's a balance between wearing down on pavement versus being destroyed by an off-road hazard.
Specific Use Cases: Which Tyre Fits Your Lifestyle?
To truly pinpoint which tyre is best, HT or AT, for you, it’s vital to consider your typical driving scenarios. Let’s break down some common profiles:
The Daily Commuter: Pavement is Your Playground
If your vehicle spends the vast majority of its time navigating city streets and highways, and your idea of adventure is finding a new coffee shop, then HT (Highway Terrain) tyres are almost certainly your best bet. You'll benefit from:
- A quieter, more comfortable ride, reducing fatigue on long drives.
- Better fuel economy, saving you money at the pump.
- Generally longer tread life on paved surfaces.
- Responsive handling for everyday driving.
For this user, the added aggression and potential noise of AT tyres would be unnecessary and a detriment to their daily driving experience.
The Weekend Warrior: Occasional Off-Road Adventures
This is where the decision becomes more nuanced. If you enjoy weekend camping trips, occasional visits to national parks with unpaved access roads, or simply want the confidence to handle a light trail, AT (All-Terrain) tyres offer a compelling advantage. You gain:
- Significantly improved traction on dirt, gravel, and mud.
- Enhanced durability and puncture resistance for off-road hazards.
- The ability to explore beyond paved surfaces with greater confidence.
However, you must be prepared for some compromises on the road: increased noise, a slightly less refined ride, and potentially lower fuel efficiency. If the off-road capability is used frequently enough to justify these trade-offs, ATs are the way to go.
The Off-Road Enthusiast: Serious Trail Exploration
For those who regularly engage in serious off-roading, mud bogging, rock crawling, or extensive backcountry exploration, standard AT tyres might even be a compromise. In these scenarios, you might consider more aggressive **Mud-Terrain (MT)** tyres. However, for a balanced approach to frequent but not extreme off-roading, robust AT tyres are still an excellent choice. They provide the necessary grip and durability without the extreme compromises in on-road manners that MT tyres often bring.
The All-Weather Driver: Dealing with Snow and Ice
When considering weather, both HT and AT tyres have limitations in severe winter conditions. Standard HT tyres are generally not designed for heavy snow or ice. Their tread patterns lack the deep sipes and aggressive biting edges needed for optimal grip. Some HT tyres come with a "three-peak mountain snowflake" (3PMSF) symbol, indicating they meet certain winter performance standards, but they are still primarily designed for pavement.
AT tyres, with their more open tread patterns, can offer better traction in light snow and slush than many HT tyres due to their ability to clear debris. However, they are not a substitute for dedicated winter tyres. For true winter performance, particularly in areas with frequent snow and ice, a set of dedicated **Winter Tyres** or **All-Weather Tyres** (which are different from All-Terrain) is highly recommended. All-Weather tyres often carry the 3PMSF symbol and are designed to perform reliably across a wider range of temperatures and conditions, including moderate snow, while still offering decent on-road manners.
My personal experience: I live in an area that gets a decent amount of snow. While my AT tyres got me through some moderately snowy situations with careful driving, they were no match for the sheer confidence and stopping power of dedicated winter tyres during a blizzard. If snow and ice are a major concern, I'd strongly advise against relying solely on either HT or AT tyres. Investing in a seasonal set or a good set of all-weather tyres is a much safer bet.
Understanding Tyre Markings and Symbols
To further aid in your decision about which tyre is best, HT or AT, it’s useful to understand some common markings you'll find on the sidewall. These can provide clues about a tyre's intended purpose and capabilities.
- "M+S" (Mud and Snow): This marking is often found on AT tyres and some HT tyres. It indicates that the tyre meets certain geometric design requirements for mud and snow traction. However, it’s a very basic standard and doesn't guarantee exceptional performance in severe winter conditions.
- "Three-Peak Mountain Snowflake" (3PMSF): This symbol is a much more rigorous standard, indicating that the tyre has undergone specific testing and meets performance criteria for severe snow conditions. Tyres with this symbol are often considered true winter tyres or capable all-weather tyres. You'll be more likely to find this on dedicated winter tyres or some higher-spec all-weather tyres, and less commonly on standard HT or AT tyres, though some manufacturers are now offering ATs with this rating.
- Load Index and Speed Rating: These numbers indicate the maximum load the tyre can carry and the maximum speed at which it can safely operate. These are critical for safety and should always be matched to or exceed your vehicle's requirements.
- Treadwear, Traction, and Temperature Grades (UTQG): This system provides a standardized way to compare tyres.
- Treadwear: A higher number indicates a longer-lasting tyre (e.g., 500 is expected to last longer than 300).
- Traction: Graded from AA (best) to C, indicating the tyre's straight-line wet braking traction.
- Temperature: Graded from A (best) to C, indicating the tyre's resistance to heat buildup.
While these markings are helpful, they are just one piece of the puzzle. The overall tread design, compound, and construction are far more indicative of a tyre's intended performance category (HT vs. AT).
The Compromise: Can AT Tyres Be Quiet?
It's a common question: "Can I get the ruggedness of AT tyres without the excessive noise?" The answer is yes, to a degree. Tyre manufacturers are constantly innovating. Many brands now offer "hybrid" AT tyres or AT tyres specifically designed with on-road refinement in mind. These tyres often feature:
- Advanced Tread Design: Computer-optimized tread blocks with variable pitch patterns can help break up resonant frequencies, reducing noise.
- Quieter Sipes: Strategic placement and shaping of sipes can minimize road noise while still providing necessary traction.
- Damping Compounds: Some compounds are engineered to absorb more road vibration.
While these tyres might still be slightly louder than a pure HT tyre, they offer a significantly quieter and more comfortable experience than older-generation AT tyres. If you’re leaning towards AT but are concerned about noise, look for AT tyres marketed for their on-road refinement or "next-gen" designs.
My Own Journey: How I Chose Between HT and AT
My decision to switch from HT to AT on my primary vehicle wasn't taken lightly. For years, I drove a compact SUV that was primarily used for commuting and occasional grocery runs. HT tyres were the obvious choice – they were quiet, fuel-efficient, and offered predictable handling. I never felt the need for anything more.
Then came the purchase of a larger, more capable SUV, and a lifestyle change that included more camping, visiting more remote family, and exploring state parks. My HT tyres, while still competent for the daily commute, started to feel inadequate. I found myself hesitating before driving down gravel roads, always worried about getting stuck or damaging a tyre. The moment of truth arrived during a camping trip where the unpaved access road had turned into a muddy mess after some rain. My HTs were spinning uselessly, and I had to rely on the kindness of a stranger with ATs to pull me out. That was an embarrassing and eye-opening experience.
So, I made the switch. I researched extensively, looking for AT tyres that offered a good balance. I read reviews, compared tread patterns, and spoke with tyre shops. I ended up with a set of AT tyres that are known for being relatively quiet for their class. Yes, there's a discernible hum at highway speeds that wasn't there with the HTs, and my fuel economy dipped by about 1-1.5 MPG. However, the confidence and capability they've given me on dirt roads, in light snow, and even just on wet grass have been invaluable. For my current needs, the trade-offs were absolutely worth it.
This personal journey highlights why there's no single "best" tyre. It’s about finding the best fit for *your* unique circumstances. If I were still in my previous driving phase, I'd likely still be on HT tyres.
Common Misconceptions about HT and AT Tyres
There are a few common misunderstandings that often lead people to make the wrong tyre choice. Let's clear those up:
- "AT tyres are always noisy and uncomfortable." While traditionally true, modern AT designs have significantly improved on-road refinement. Some ATs are remarkably quiet and comfortable for their capabilities.
- "HT tyres are dangerous off-road." For light, dry, hard-packed dirt, HT tyres might suffice. But for anything loose, wet, or uneven, their lack of grip and durability makes them significantly less safe than AT tyres.
- "AT tyres wear out too quickly." This depends heavily on the specific tyre and the driving conditions. While they might wear faster on pure pavement than HTs, their puncture resistance can make them last longer in mixed-use scenarios where HTs would be easily damaged.
- "M+S is equivalent to a dedicated winter tyre." Absolutely not. M+S is a basic designation. The 3PMSF symbol is the true indicator of severe snow performance.
- "All-Terrain means good in all conditions, including deep snow and ice." All-Terrain means good on *all types of terrain*, not necessarily good in *all weather conditions*. For severe winter, dedicated winter tyres are superior.
Factors to Consider When Making Your Choice
To reiterate, the decision of which tyre is best, HT or AT, hinges on several key factors. Here’s a checklist to help you evaluate:
- Your Primary Driving Environment:
- Mostly paved roads (highways, city)? -> Lean HT
- A mix of paved and unpaved (gravel, dirt roads)? -> Lean AT
- Frequent or extreme off-roading? -> Consider MT or specialized AT
- Your Vehicle Type:
- Sedan, compact SUV, crossover primarily for commuting? -> HT is often sufficient
- Truck, larger SUV, or vehicle used for hauling/towing and occasional off-road? -> AT offers more versatility
- Your Tolerance for Noise and Roughness:
- Highly sensitive to road noise, prioritize a plush ride? -> HT
- Can tolerate some road noise for added capability? -> AT
- Your Fuel Economy Priorities:
- Maximizing MPG is critical? -> HT
- Willing to sacrifice some MPG for versatility? -> AT
- Your Climate and Weather Conditions:
- Mild winters, minimal snow/ice? -> HT or AT might suffice
- Frequent snow, ice, or harsh winters? -> Consider dedicated winter tyres or all-weather tyres in addition to or instead of HT/AT
- Your Budget:
- AT tyres can sometimes be more expensive than comparable HT tyres, and the potential dip in fuel economy adds to the long-term cost.
- Tire Longevity Expectations:
- Pure pavement longevity? HT often wins.
- Durability against off-road damage? AT has an advantage.
Frequently Asked Questions (FAQs) about HT vs. AT Tyres
Q1: How much does fuel economy typically decrease when switching from HT to AT tyres?
The decrease in fuel economy when switching from HT to AT tyres can vary significantly depending on several factors, including the specific tyre models, the size of the tyres, your vehicle, and your driving habits. However, a general estimate is that you might see a reduction of anywhere from 1 MPG to as much as 3 MPG. For instance, if you were getting 25 MPG with HT tyres, you might see anywhere from 22 MPG to 24 MPG with AT tyres. This is primarily due to the increased rolling resistance of AT tyres. Their more aggressive tread pattern and often softer rubber compound require more energy from the engine to rotate. Additionally, the increased tread depth and weight of some AT tyres can also contribute to this reduction. If fuel efficiency is your absolute top priority, this is a significant consideration. However, for many drivers who need the added capability of AT tyres, this trade-off is acceptable and manageable.
Q2: Are AT tyres significantly louder than HT tyres?
Yes, AT (All-Terrain) tyres are generally noticeably louder than HT (Highway Terrain) tyres. This is a direct consequence of their design. AT tyres feature larger, more aggressive tread blocks with wider spaces between them. This open tread pattern is what allows them to grip effectively on loose surfaces like dirt, mud, and gravel. However, these larger blocks and voids create more air turbulence and slapping sounds as they come into contact with the pavement, resulting in increased road noise. You'll typically hear a consistent hum or roar, especially at highway speeds. HT tyres, on the other hand, have a more continuous, symmetrical tread pattern with smaller, tightly packed blocks. This design minimizes air disruption and maximizes contact with the road, leading to a much quieter and smoother ride. While modern AT tyre technology has made strides in reducing noise through variable tread block designs and advanced compounds, they will almost always be louder than their HT counterparts. If you are particularly sensitive to noise, this is a key difference to consider.
Q3: Can I use AT tyres all year round in most climates?
AT (All-Terrain) tyres offer a good degree of versatility and can be used year-round in many climates, particularly those that don't experience severe winter conditions. Their open tread patterns can provide better traction in light snow and slush compared to many standard HT tyres, thanks to their ability to clear away debris and bite into softer surfaces. However, it's crucial to understand that AT tyres are not a substitute for dedicated winter tyres in areas with heavy snow, ice, or extreme cold. While some AT tyres may carry the "M+S" (Mud and Snow) designation, this is a relatively basic standard. For reliable performance in severe winter conditions, tyres with the "Three-Peak Mountain Snowflake" (3PMSF) symbol are recommended. These tyres have been specifically tested and proven to perform in challenging snow and ice environments. If your climate regularly sees significant snowfall or icy roads, you might consider a set of dedicated winter tyres for the colder months, or opt for a high-quality all-weather tyre that carries the 3PMSF symbol and offers a better balance across all seasons.
Q4: How do I know if my vehicle can handle AT tyres?
Most modern vehicles, especially trucks and SUVs, are designed to handle AT (All-Terrain) tyres without issue. The key consideration is ensuring that the AT tyres you choose are the correct size and have the appropriate load index and speed rating for your specific vehicle. This information can typically be found on a sticker inside the driver's side door jamb or in your vehicle's owner's manual. If your vehicle came from the factory with AT tyres, then switching to another set of AT tyres in the same or a comparable size is generally straightforward. If your vehicle came with HT tyres, switching to ATs is usually possible, but it's wise to confirm that the dimensions (tire diameter, width, and aspect ratio) are compatible with your vehicle's suspension and bodywork. Some larger AT tyres might require minor modifications or may rub against the fenders or suspension components, especially when the suspension is compressed or when turning. It’s always a good idea to consult with a reputable tyre professional or your vehicle manufacturer if you are unsure about fitting significantly different tyre sizes or types.
Q5: How much longer do HT tyres typically last compared to AT tyres on pavement?
On pure pavement, HT (Highway Terrain) tyres typically offer a longer tread life than AT (All-Terrain) tyres. This is due to the harder rubber compounds used in HT tyres, which are specifically formulated to resist wear on abrasive asphalt surfaces. Their more consistent tread pattern also tends to wear more evenly on smooth roads. Treadwear ratings (found on the UTQG label) can provide a benchmark, with HT tyres often having higher treadwear numbers than comparable AT tyres. For example, an HT tyre might have a treadwear rating of 500-700, while an AT tyre might range from 300-500. While this suggests HT tyres last longer, it's essential to consider the context. If your driving involves frequent encounters with gravel, rocks, or other off-road hazards, an HT tyre is far more susceptible to punctures, cuts, and chips that can prematurely end its life. In such mixed-use scenarios, a more durable AT tyre might actually outlast an HT tyre in real-world conditions, despite having a lower pavement treadwear rating. Therefore, "longevity" should be considered in relation to the intended use.
Conclusion: Making the Informed Choice for Your Vehicle
Deciding which tyre is best, HT or AT, boils down to a realistic assessment of your driving habits and needs. There's no universal winner; there's only the best tyre for *you*. If your world is predominantly paved, and comfort, quiet, and fuel economy are paramount, the HT tyre is your champion. It's designed to excel in these conditions and will likely serve you reliably and efficiently.
However, if your adventures beckon you off the beaten path, even just occasionally, and you crave the confidence of knowing your vehicle can handle a bit of the rough stuff, then the AT tyre offers a compelling blend of on-road usability and off-road capability. Be prepared for some compromises in noise and fuel economy, but the added versatility and peace of mind can be well worth it. As I've learned through my own experiences, the right tyre can transform your driving experience, opening up new possibilities and ensuring safety and confidence on whatever road lies ahead.
Ultimately, take the time to honestly evaluate your typical journeys. Consider the type of surfaces you encounter most often, the weather you drive in, and your personal preferences for ride comfort and noise. Consulting with a knowledgeable tyre professional can also provide invaluable insights tailored to your specific vehicle and local conditions. By understanding the strengths and weaknesses of both HT and AT tyres, you can confidently make the choice that best suits your driving lifestyle.
