This special tread and compound will decrease performance in cold climates and on ice and snow. Note: Do not use summer-only tires in winter conditions, as it would adversely affect vehicle safety, performance, and durability. Use only GM-approved tire and wheel combinations. Winter tires are designed for increased traction on snow- and ice-covered roads. Consider installing them if frequent driving on ice- or snow-covered roads is expected.
See your dealer for details regarding winter tire availability and proper tire selection. With winter tires, there may be decreased dry-road traction, increased road noise, and shorter tread life. Scheduling service is quick and easy. Make your next appointment online by locating a Certified Service dealer near you.
So, when looking at all-season tires, the strengths are also the weaknesses. If you periodically experience extreme weather conditions, all-season tires might not be the most ideal in those times of the year.
See Prices. The Coop er CS5 Grand Touring is a very popular all-season model that uses this technology for improved traction during hard cornering, acceleration, and braking. The high-grade silica rubber offers longer tread wear that is effective in wet or dry conditions.
Dynamic Range Technology — Tires with Dynamic Range Technology use a silica tread compound and asymmetric design meant to provide optimal grip on dry, wet, icy, and snowy road conditions.
More specifically, this technology was created to have a stronger tolerance for extreme temperatures and deliver extra-long mileage durability for passenger vehicles.
This versatile tire is designed to remain flexible and grippy in extreme temperatures. Highway tires are meant to be used primarily on paved roads. They are strictly intended for commuting, typically come with long mileage warranties, and are designed for smooth, quiet rides with predictable handling on cars, trucks and SUVs.
Most highway models feature independent tread blocks and multiple sipes around the tire for optimal on-road performance with traction in moderate weather conditions. See Tires. Additionally, the silica compound works to shorten braking distance for excellent fuel economy,. This line also uses a 5-rib tread pattern and wide lateral shoulder grooves to prevent hydroplaning. All-terrain tires are designed to have a high level of traction on all kinds of roads and surfaces.
Models at fall under this type of tire have a combination of open-tread designed for both off-roading and handling on paved streets. The most important thing to keep in mind with all-terrain tires is they are meant for multiple purposes.
So, if you only drive on paved roads and highways, this is not a good option. Cooper prides itself in the AT3 line being perfect for both the everyday commute and weekend adventures.
The silica-based all-weather compound and all-terrain tread design give these tires a leg up in a wide range of temperatures and environments. Sport tires are used on high-performance light trucks, and are designed for excellent handling, performance, and of course, looks.
Thanks to a larger contact patch area, sport tires provide excellent grip on dry paved roads. This number shows the relation of the tire height to width in a percentage. Self-Supporting Technology — Another breakthrough from Dunlop, this technology uses a special sidewall construction that allows continued driving on a flat tire for up to 50 miles at up to 50mph in normal driving conditions. This model is designed for high performance with all-season versatility on wet, dry, and mild wintery roads.
While all-terrain tires are meant to provide a good driving experience in both on and off-road situations, mud tires, as you could imagine, are specifically designed as off-road tires.
Summer tires are designed specifically to deliver dry- and wet-weather traction in moderate or warm weather. They sharpen steering response, increase cornering traction by an order of magnitude, and stop your vehicle in much less distance. But they do so at a cost: most summer tires only work well at temperatures of about 40 degrees Fahrenheit and above. As outside temps fall toward freezing, the tires can feel skittish and behave inconsistently; they lose a large portion of their grip to the point that they act like they are on a wet or even icy road.
More than one driver of a powerful car, unaware of the temperature sensitivity of its summer tires, has lost control and crashed on a cold day. As with all-season tires, summer rubber comes in several varieties. Tire Rack divides these tires into three main groups by escalating capability: ultra-high performance on the bottom rung, followed max performance and extreme performance.
Called "snow tires" in the past, winter tires are designed to provide maximum traction in snow and in slippery winter conditions—and the traction they provide in those situations is not matched by any other category of tire. Even an all-wheel-drive vehicle on all-season tires cannot match the stopping or turning capability of a similar two-wheel drive vehicle fitted with four winter tires, a point we have proven in our own winter-tire testing.
Winter tires are designed to work well in the cold-weather months, but they don't handle or wear as well as all-season or summer tires once the weather warms up. They should be considered as a second set of tires for your vehicle if you live where snow flies annually. We fit all of our long-term test vehicles with winter tires and they've proven their worth many times over. Why use winter tires? If you live in the northern states, we recommend purchasing a set of winter tires.
Their deep treads are engineered to deliver a significant traction improvement, and do they ever work. You'll feel safer and be safer, not to mention more relaxed when driving in snow.
Retailers such as Tire Rack will sell you a set of snows mounted on steel wheels that you can swap on when winter rolls around. Here at Car and Driver , we swear by them.
Most consumers choose to replace the worn tires on their vehicle with something equivalent in size and capability. This makes a lot of sense; your car was engineered to work well on the type and size of tires it came on, so fitting an identical or similar replacement set would maintain the performance and safety your vehicle was designed to deliver.
We'll get to upgrading later on. To inform your decision process, you'll need to know your vehicle's tire size and speed rating, and you'll also want to consider how many miles you'll get out of any new tires you are considering this is called tread wear. Much of that information is printed on the sidewalls of the tires that are on your car right now. It's also available in most owner's manuals, online, and at tire dealers.
We suggest cross-checking those sources to make sure you've got the right information. Here's how to read the most important data imprinted on your tires' sidewalls. For an in-depth look at how to read all of the information on a tire sidewall, click here. KEY: 1 Tire width; 2 Aspect ratio; 3 Radial-tire designation; 4 diameter; 5 Load rating with speed rating; 6 Heaviest spot on tire; 7 Tread-wear rating; Traction and temperature ratings; Mud-and-snow or three-peak-mountain rating; 12 Vehicle-specific marking; 13 Tire-materials list and manufacturing information.
If you're going to replace your tires with something equivalent, you will need to know the proper size. The first number indicates the width of the tire at its widest point in millimeters. The number after the slash is what's called the aspect ratio, which indicates how tall the sidewall is as a percentage of the width. The higher the number, the taller the sidewall.
The squat tires fitted to sports cars and muscle cars, called low-profile tires, have aspect ratios of 30— Family sedans and SUVs are in the range or taller. The final number in the series is the diameter of the wheel in inches that the tire must mount to.
The "R" indicates it's a radial tire, which virtually all of today's tires are. Tires also carry a speed rating, which indicates not only how fast they can safely go for an extended period of time, but also the overall performance potential of the tires. Tires for high-performance cars have a higher speed rating than those for mainstream family sedans and SUVs.
