Understanding The Types Of Tires

Types Of Tires

Shopping for tires is much like shopping for a pair of pants, all are pants but not all will fit you or work in every weather or match your tastes or be as utilitarian as you’d like them to be. Summer and all-season tires take the place of casual pants that you can wear anytime but if you want something more focussed and athletic, like track pants then performance tires shine bright. Formal pants are like grand touring tires: look great yet comfortable. Now, as winter strikes and cold sets in, you can’t be sporting a pair of casual pants. Instead, you need winter clothes that keep you warm similar to what winter tires do for snow and ice driving. As for size, if your pant size is M you can’t be wearing an XL. Similarly, car and truck tires are differently sized to accommodate different wheel sizes and vehicle loads.

1. Different Tire Types

The type of tire for your vehicle can be differentiated mainly based on the vehicle. Car tires are solely intended for sedans, CUVs, minivans, hatchbacks and other subcompact cars. Truck tires have similar characteristics to car tires but are intended for larger wheels and are designed to bear heavier loads, evident from the sidewall height and width of the tire. Trucks tires are used on SUVs, light trucks, off-roaders, ATVs and other such recreational vehicles. 

2. Car Tires

2.1. Summer

Summer tires work well in dry and wet conditions during warm weather and are often referred to as three-season tires. They are ideal for use on dry and wet roads and provide great handling and driving dynamics as well as optimal stopping distances on dry tracks. They are only suited to be used during warmer and moderate weather and stiffen up when the temperature drops to freezing. These do not perform well in winters with snow and ice-covered roads. Since they are only intended for use during summer months, the tires need to be switched out when winter strikes. 


2.2. All-Season

2.2. All-Season

Most vehicles come equipped with All-season tires from the factory as they are the perfect balance between summer and winter tires. All-season tires, as the name suggests, are designed for summer months with warmer weather, rainy season and also work well in moderate winter conditions. However, these tires do not cope well with snow and ice-covered roads and can only perform at temperatures above 7℃ (45℉). 

All-season tires provide good traction, wet-weather capability, comfortable ride and acceptable all-year performance. They also have great treadwear ratings, which allow them to last longer. All-season tires can come with a treadwear warranty between none - 65,000 to 160,000 km and speed ratings of S (112 mph) and T (118 mph).


2.3. All-Weather

2.3. All-Weather

All-weather tires are a subset of all-season tires and provide additional benefits as compared to all-season tires. All-weather tires can perform even in cold temperatures similar to winter tires while still providing all-year-round traction, handling and performance. These tires are even rated with winter tire standards (three-peak mountain snowflake pictograph) allowing them to be used in extreme winter conditions below freezing temperatures on snow-covered roads. However, they cannot outperform specialized winter tires, especially at very low temperatures (-10℃ or 14℉) and on ice. 

All-weather tires are ideal for use in Canada, where the temperatures reach both extremes. These tires can last longer and perform well in every type of weather condition while providing a comfortable ride. The speed ratings and treadwear warranty of these tires are similar to all-season tires. 

2.4. All-Season Performance / Touring

These tires perform better than standard all-season tires and offer increased handling and sharper cornering ability with higher speed ratings and shorter braking distances. These tires are geared towards people who prefer a sportier ride with all-year performance and long-lasting tread. These are often referred to as touring or grand touring all-season tires. The speed rating is within H (130 mph) and V (149 mph) with a treadwear warranty ranging from none - 65,000 to 130,000 km

2.5. Ultra-High-Performance

2.5. Ultra-High-Performance

For absolute performance-oriented vehicles like sports and sports sedans, all-season and summer UHP tires are used. These tires have very high-speed ratings and provide exceptional handling dynamics, swift steering responses and minimal stopping distances. However, the performance benefits come as a compromise to ride quality, tread life and winter traction. All-season UHP provides some snow traction at the expense of dry and wet grip, while summer UHP tires have no winter capabilities. 

UHP tires have speed ratings of ZR (149-plus mph), W (168 mph) and Y (186 mph) with treadwear warranty ranging from none - 50,000 to 100,000 km.

3. Truck Tires

3.1. All-Season SUV/Truck

All-season SUV and truck tires are designed specifically for increased load capacities while offering adequate all-year performance. These all-season tires are tuned for SUVs and trucks and offer performance, tow-ability and off-road driveability based on the vehicle’s capabilities. The speed ratings vary from S (112 mph), T (118 mph), to H (130 mph) with treadwear warranties of none - 65,000 to 130,000 km.


3.2. All-Terrain Truck

3.2. All-Terrain Truck

Such tires have larger treads that allow them to be used on unpaved land and snowy surfaces. All-terrain tires are used on heavy-duty vehicles and off-roading trucks and SUVs. The speed rating is most commonly S (112 mph). The treadwear warranty can vary from none to 80,000 to 100,000 km.

4. Winter Tires

During winter, the rubber compounds in most tires, like all-season and summer, start to harden and stiffen up, which reduces their traction and road grip. This is why winter tires, previously known as snow tires, are used that provide unparalleled winter traction and handling. Winter tires can sustain extremely low temperatures such as -40℃ (-40℉) while retaining flexibility and enough grip to handle and brake on ice and snow stacked roads. No other tires can outperform winter tires when it comes to driving in severe ice and snow conditions in severely cold weather. Due to their specialized winter capabilities, these tires do not work in any other season and wear faster on clear roads. 

Winter tires are recognized by a three-peak mountain snowflake design that is etched into the tire sidewall and signifies that the tire has met minimum industry requirements for severe winter usage. Canada is prone to inclement weather during the winter months and so the use of winter tires is recommended and even mandated by law in few Canadian provinces.

Winter tires have low-speed ratings - Q (99 mph) but come with no precise treadwear warranties. 


4.1. Winter Performance

Similar to UHP all-season and summer tires, performance winter tires offer the best driving dynamics on winter roads while retaining their winter capabilities. They offer a better grip on icy roads as compared to standard winter tires. Speed ratings for these tires can start from H (130 mph) and go higher. These also have no stable mileage, much like regular winter tires.

5. FAQs

Q) What Type Of Tires Do I Need For My Car?

The tire that is best for you depends on a few factors such as your driving style, the weather you drive in and what type of roads you drive on. We have compiled a comprehensive tire buying guide that can help you realize the type of tire best suited for your needs. 


Q) How Long Should Tires Last?

The life of a tire can vary based on many aspects like the tire type, vehicle, driving conditions, etc. A treadwear rating is present on most tires as part of the UTQG codes that tell you how wear-resistant a tire is. The larger this number, the more wear-resistant the tire will be and hence will last longer. Most manufacturers also showcase treadwear warranties that can provide some light on the subject. Although these warranties only provide an estimate and claiming such warranties is an involved task. 


Q) What Do The Tire Codes Mean?

Every tire found in North American markets has three sets of codes: tire specifications, DOT and UTQG codes. The tire specification identifies tire and wheel size along with its speed and load indexes. The DOT code is mainly for the manufacturer, but it can help you determine your tire’s date of manufacture. Lastly, the UTQG codes showcase the various tire parameters such as treadwear, temperature and traction rating. You can learn in-depth about each tire code in our tire specification article.


Q) How To Find The Right Tire Pressure And Do Different Tire Types Have Different Pressure Ratings?

The correct tire pressure can be found either on the tire placard located on the driver/passenger door sill or comes with the tire. It is usually recommended to stick to the vehicle manufacturer specifications found on the placard, as these numbers are determined specifically for each car. The tire pressure can also vary based on the application like highway or off-road driving requires different tire pressures for optimal performance. For highway driving, you must have your tire pressures set at the recommended psi, whereas for off-roading most people prefer  lower tire pressure as that helps in gripping the uneven surface better. The tire pressure can also vary across the font and rear wheels and it is best to consult your owners manual or tire placard for more info. 


Q) Can You Have Different Types Of Tires On Your Car? Is Tire Mixing A Good Idea?

Most vehicles come with the same tire type, tread pattern, size, load index and speed rating on all wheels and manufacturers recommend using the same tires on all four wheels. Very few vehicles have exceptions from manufacturers, and only in such cases can you opt for a mixed set of tires. Mixing tires is dangerous as it sacrifices vehicle handling due to the varied traction at every wheel and also causes rapid tire wear. This means you will be shopping for tires more often if you mix them rather than using the same type on all four wheels.
