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 UTQG 720 AA mean?
A UTQG rating is made up of a three-digit number and two letters or letter groups. For example, a tire might have a 720 A A rating. The first letter or group of letters is the traction rating. The best grade is AA, followed by A, B and C. The better the grade, the better the tire will stop in wet conditions.
What does UTQG 800 AA mean?
Treadwear. The treadwear marking demonstrates how long a tire can last. Treadwear has a range between 100-1000, where, for example, an 800 UTQG tire will last twice as long as a 400 UTQG tire.
What does UTQG 500 mean?
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.
How do you read a UTQG?
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. So the tire rated at 400 would wear four times longer than the government’s mandated tire.
What are the 3 UTQG rating?
The UTQG rating is made up of three components, treadwear, traction and temperature.
Is a treadwear of 640 good?
On the other end, today’s more durable tires carry UTQG tread wear grades of 640, 720 or even 820—meaning they will last up to six times as long as those expensive high-performance lines. Long-lasting tires when new sometimes carry tread wear warranties of 60,000 to 80,000 miles.
Is 560 treadwear good?
For example, four models that had modest tread-wear grades (520 to 560) and warranties (65,000 to 75,000 miles) scored fair in CR’s wear-test ratings. Likewise, a tire with a 700 UTQG grade and an 80,000-mile warranty had excellent tread wear in the tests.
Is a higher treadwear number better?
Tires across the treadwear range, which normally ranges from 800 down to 100, provide the grip and longevity needed in applications from long-endurance trailer tires, to premium daily tires, to full-on racing slicks. The lower the number, the higher the grip. The higher the number, the longer they last.
What does treadwear rating mean?
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.
How many miles is a 700 treadwear rating?
A general rule of thumb sometimes used is that an average driver with an average vehicle can typically estimate the tread life of a tire by multiplying the UTQG treadwear rating by 100. For example, a tire with a treadwear rating of 700 may last approximately 70,000 miles.
Is 800 treadwear good?
A tire with a treadwear rating of 800 should theoretically last about twice as long as a tire with a treadwear rating of 400. A longer life tire will be designed with a harder rubber compound to withstand wear better.
What speed rating is W?
A relatively new addition to the speed rating chart, tires with speed rating “W” can achieve a maximum sustained speed of 168 mph (270 kph).
Which traction grade signifies the best traction?
Traction (the safety rating)
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.
What is the purpose of a Sipe?
A sipe, also called a “kerf” is a small slit in the tire’s tread block that creates additional tread surface area for increased grip in wet, icy and snowy conditions.
What does UTQG 300 AA A mean?
Uniform Tire Quality Grade (UTQG) Standards | Tire Rack
conditions. If the test tire is expected to last as long as the reference tire, it receives a UTQG Treadwear grade of 100. If it is expected to last twice as long, it would receive a grade of 200. 300 means it is expected to last three times as long, and so on.
