AA
Traction is graded “AA” (highest), “A,” “B” or “C” (lowest). While more than three quarters of all tires are rated “A” or better, only 3 percent are rated “AA.” Just over 20 percent are “B” and only one line of tires is rated “C.”
What is traction rating A?
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.
Should I get H or V rated tires?
To support running at higher speeds, V-rated tires will have a stiffer sidewall and slightly firmer ride than H-rated tires. For normal driving conditions the H-rated tire will provide a more comfortable ride and the V-rated should give slightly better handling.
What does tire traction B mean?
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. C rates at a maximum of between 85 mph to 100 mph. Tires that cannot grade up to C or higher cannot be sold in the US.
Which traction grade signifies the best traction?
A traction grade tells you how well your tire can stop in wet conditions. 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.
Is a higher treadwear rating better?
Tread wear (the durability rating) This number designation is designed to give you a picture of the durability or life you can expect from your tire. The higher the tread wear number, the longer the tread wear will last. In this case, a higher number is better than a lower number.
What does treadwear rating mean?
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one half times as well on the government course as a tire graded 100.
Can you mix H and V-rated tires?
Just remember, never mix and match tires with different speed ratings on your vehicle. This will cause major problems with the handling of your vehicle. If tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle, regardless of which axle is driven.
Are H-rated tires good?
Sports cars may get better handling with a ZR tire. H-Rated Tires: This is a perfect, average tire for most sedans and commuter vehicles.
Which traction grade is the highest?
The traction grade looks at the level of grip on a wet surface. Most ultra-high-performance tires achieve the best grade: AA.
What does treadwear mean on a tire?
What does tire rating traction mean?
Traction: Tire traction is rated AA, A, B or C, with AA at the top of the scale. This rating is based on the tire’s ability to stop a car on wet concrete and asphalt. It does not indicate the tire’s cornering ability.
What is the UTQG rating on tires?
The UTQG rating system originated in the US as a way to help consumers make more informed tire-buying decisions. Tire manufacturers give their own tires a grade for treadwear, traction and temperature. Together, these numbers makes up a tire’s UTQG rating—a three-digit number plus two letters.
What does traction rating mean?
Each tire has a tire traction rating that grades how well a new tire stops on wet roads when properly inflated. Each result is basedon controlled tests and graded with AA, A, B or C ratings. Traction ratings with a AA grade means a tire has the best possible traction while a C grade denotes the lowest.
What is temperature rating on tires?
Tire temperature rating grades a correctly inflated tire’s ability to resist and properly disperse heat. A tire temperature grade ranges from A to C, with C being the lowest possible score under federal regulations. A tire assigned with an A score means it runs the coolest while one graded C runs the hottest.
