What is the best traction rating for a tire?
AA
The highest traction grade is AA, followed by A, B, and C. Tires with an ‘AA’ traction rating should stop at a much shorter distance than a tire with a ‘C’ rating.
What does 400 AA mean on a tire?
The 400 is tread wear which represents the tire’s comparative wear when measured against the governments mandated tire, which is rated at 100. So the tire rated at 400 would wear four times longer than the government’s mandated tire. However, please don’t link treadwear grades with your projected tire mileage.
What does traction rating a mean on a tire?
Temperature grades range from A to C, with A being highest rated and therefore most resistant to heat generation. Tires graded A effectively dissipate heat up to a maximum speed that is greater than 115 mph. B rates at a maximum between 100 mph and 115 mph.
What is H and V rated tires?
The most common ratings are S and T (sedans, minivans, light trucks); H (some passenger cars, sports cars, coupes, some light trucks); N, P, Q and R (light trucks); and V, W and Y (high-performance and some electric vehicles). Most winter tires have Q, S or T speed ratings.
Is tire traction of B good?
Traction also receives letter grades that indicate how well it stops. A tire having a higher grade should allow a car to stop on a wet road in a shorter distance than a tire with a lower grade. Traction is graded “AA” (highest), “A,” “B” or “C” (lowest).
What does treadwear 500 mean on a tire?
If the tire being tested gets a 500-tread wear rating, that means it’s expected to take five times as long to wear out as the control tire. The tread wear grade designation is defined when the tire is run a 640 kilometer course for 11,520 km, with tread depths being measured every 1,280 to give a projected tread life.
What does 600 AA mean on tires?
In basic terms, and in the spirit of the concept, the higher the UTQG treadwear rating, the greater the tire life. A tire with a “600” treadwear rating is forecasted to last twice as long as a tire with a “300” rating, and should accumulate three times the mileage of a “200” rated tire.
What does a treadwear of 500 mean?
What does traction AA mean?
Traction. Traction markings indicate how well a tire will perform in wet conditions. The traction rating can be AA, A, B or C. AA is the highest level of wet traction and C is the lowest.
Which is better T or H speed rating?
The “T” or “H” on tires pertain to their speed ratings. A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.
What is a good treadwear number?
Tires with treadwear ratings of 350 or less tend to have some performance pretentions, but for serious drivers and competitive racers, the only tires they will ever consider have treadwear ratings of 200 or less.
