utqg tire rating
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.
Is UTQG 820 AB 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.
What does 500 AA A mean on tires?
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.
What does treadwear 800 mean on a tire?
Treadwear is not based on any one industry or government standard. The higher the number the longer the tire should last compared to similar tires from the same manufacture with lower numbers. A tire with a treadwear rating of 800 should theoretically last about twice as long as a tire with a treadwear rating of 400.
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.
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.
Which is better H or T rated tires?
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).
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.
What does UTQG AB mean?
The Uniform Tire Quality Grading is a comparative assessment applied to most car tires (excluding winter tires) to help consumers make informed decisions. The manufacturers grade the tires themselves for temperature, traction, and treadwear.
What does the V mean on tires?
SPEED RATING V
Once the highest speed rating a tire could have, “V” used to represent a maximum of 149 mph (240 kph) or more. Nowadays, it means 149 mph but no higher.
What’s the best speed rating for tires?
As manufacturers developed bigger and better tires, it became necessary to regulate performance at standardized speeds to ensure safety. The “Limited V” category of 250 km/h (149 mph) was then created, and eventually the “Z” speed rating was added as the top speed rating.
How many miles is a 400 treadwear rating?
For example, treadwear 400 will mean every 1/32” wears every 8,000-10,000 miles. However, hard rubber provides a rather rough ride, while softer rubber performs better and soothes the move.
What does XL mean on a tire?
If you own a car that often carries heavy loads, or is a multi-purpose vehicle’s, e.g. a minivan, it is possible that the vehicle manufacturer originally installed Extra Load (XL) or reinforced tires. These tires have stiffer sidewalls than normal tires, which allow them to support the weight of heavier vehicles.
What does AA stand for on a tire?
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 do I read my UTQG rating?
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.
How long are tires good for?
On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.
