What is a good UTQG?
Most ultra-high-performance tires achieve the best grade: AA. Most car tires get the next best grade of A; less than 22 percent of the tires have a B grade; and only one tire (out of more than 2,400 models) has the honor of a C grade.
What does UTQG 400 AA A mean?
Uniform Tire Quality Grading
“UTQG” stands for “Uniform Tire Quality Grading”. 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 does temperature b mean on a tire?
The temperature grades, from highest to lowest, are A, B and C. These represent the tire’s resistance to the generation of heat at speed. 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 does 500 AA stand for on a tire?
This rating is based off a 100-tread wear control 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.
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.
How many miles is a 400 treadwear rating?
For example: One tiremaker’s 400 treadwear grade earns only a 40,000-mile warranty, while another’s 400-level tire carries a 60,000-mile warranty.
What speed rating is R?
For tires with a maximum speed capability higher than 240 km/h (149 mph), a “ZR” may appear in the size designation. Tires with a maximum speed capability higher than 300 km/h (186 mph), require a “ZR” in the size designation….Tire Speed Rating Chart.
| SPEED SYMBOLS | ||
|---|---|---|
| P | 150 | 94 |
| Q | 160 | 100 |
| R | 170 | 106 |
| S | 180 | 112 |
What does AA mean on tires?

Is 480 treadwear good?
The bottom line on the treadwear ratings is that they are relative to the other tires a particular manufacturer makes. So a 480 in Goodyear’s line is different than a 480 in Pirelli’s line. Or Kuhmo’s line. But generally when you hit the 400’s and above, you’re into pretty durable tires.
What is the best UTQG rating for traction?
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 600 AA mean on tires?
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.
