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 a treadwear rating of 700 mean?
Under-rating a tire’s treadwear is common with ultra-high performance and R-compound tires. For example, a tire with a treadwear rating of 700 may last approximately 70,000 miles.
What does 520 treadwear mean on a tire?
In the above example, the treadwear rating is 520, so a tire tech may estimate the tread life of that tire at around 52,000 miles. It indicates a tire’s ability to stop on a straight, wet surface (not on snow/ice, and not its cornering abilities).
What does treadwear 300 mean on a tire?
Treadwear grade: A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100. Traction and temperature scores: Those scores denote a tire’s wet-stopping ability and temperature resistance. For traction, AA is best, C is worst.
How many miles is a 500 treadwear rating?
This is a lower-middle level treadwear rating. Tires with a high-end rating of over 500 should deliver approximately 80,000 miles.
What does 400 AA mean on a tire?
Uniform Tire Quality Grading
“UTQG” stands for “Uniform Tire Quality Grading”. Example: a tire with a UTQG of 400 AB. The 400 is tread wear which represents the tire’s comparative wear when measured against the governments mandated tire, which is rated at 100.
What is the highest treadwear number?
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 is a good tire treadwear rating?
What does Traction AA mean on a tire?
Temperature, the tire’s heat resistance, is stated in letters. 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).
How long will a 200 treadwear tire last?
60,000 miles
A tire rated at 200 has a projected tread life of 60,000 miles. A tire rated at 50 has a projected tread life of 15,000 miles.
Where do you find the treadwear rating on a tire?
The UTQG (Uniform Tire Quality Grade) treadwear rating, also known as a treadwear grade, is a number stamped on the tire sidewall that relates to expected tire life.
How many miles does a treadwear rating last?
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. Also asked, how many miles does a tire last?
What’s the difference between a 400 and 400 treadwear rating?
A “400” treadwear rating from Tire Manufacturer A doesn’t necessarily equal a “400” treadwear rating from Tire Manufacturer B; the mileage lifespan of the two tires under equal driving conditions could be quite different.
What do the numbers mean on a tire rating?
The first portion of the rating is a 2 – or 3-digit number that represents relative treadwear, or how long the tire’s tread is expected to last against the standard test tire. The test track they use is a 400-mile loop for a total of 7,200 miles.
