What do tyre treads do




















See our tread life mileage, and much more, in our tire ratings. Noteworthy in the findings is that more than half of the 26 all-season and performance all-season tires could last at least 65, miles; five could top 90, miles or more.

Learn how to extend tire life. Many replacement tires, especially the all-season ones that come standard on a car, minivan, or SUV, have a prorated mileage warranty. For the tires in our ratings, it is usually between 50, and 90, miles. And that price is often high relative to the frequent discounts offered by many retailers. In fact, you may be able to buy new, discounted tires for less than the price of warranty replacements. On top of that, restrictions to get your prorated credit abound.

You may also have to show receipts that verify you had the tires rotated at the prescribed intervals, usually every 5, miles, since they were new. Tires that are worn out will perform poorly on wet roads and could pose a safety risk. Our controlled tread life tests cut through the marketing mumbo-jumbo to tell you how many miles your tires will last before becoming worn out. Of course, your actual experience will vary according to the vehicle you drive, how and where you drive, routine maintenance, and other factors.

Tires have a wealth of information encoded on their sidewalls. Load index: Shorthand for the weight each tire can carry safely. The 94 here means 1, pounds per tire—pretty typical for a midsized car tire. Standard all-seasons are usually rated T mph and H mph. Winter tires may carry the letter R mph or higher. A grade of denotes a tire that will wear three times as well as a tire graded These include tread blocks, tread grooves, tread voids, wear bar, rain grooves, and siping.

Tread voids or grooves are the areas between the tread blocks which play a key role in providing the tire with traction by enabling the tread blocks to move and flex as the tires to grip the road. Additionally, these voids allow the water to escape when roadways are wet.

If your tires have a high tread-to-void ratio, they will have better wet traction and braking ability.

While the tread extends through the entire surface of the tire, the tread blocks are the raised rubber segments that make contact with the road surface;. Tire manufacturers develop these varying patterns to address specific driving needs. Here are the most common patterns. Tires with this pattern are pretty common because they are mostly used on passenger car tires, not high-performance ones. Their design has continuous ribs or independent tread blocks across the entire tread, and both sides have the same pattern.

Tires with this pattern deliver smooth driving, low rolling resistance, and high directional stability. Commonly found in all-season and winter tires, this pattern provides extra traction to handle driving on mud and snow. If you look at the pattern, the lateral grooves meet at the middle of the tire tread in the shape of an arrowhead. According to tire experts , this arrow also shows the direction in which the tire should be rotated.

The tread of the tire is something that most people take for granted. They may have a general idea that there are different tread patterns and depths, but they may not have a full understanding of the function of the tire tread. Understanding the importance of tire tread and the different tread patterns will help people drive safely and comfortably.

Regular tires have tread, unlike race car tires which do not have any tread at all. Regular tires are designed with tread to keep a car stable and safe in different road conditions. Race cars use tires without tread because smooth tires provide better traction in dry conditions. If the ground is wet, however, drivers will suddenly find themselves needing the grooved tread that siphons water away from the tires.
