What is a good tire temperature rating?
The “C” grade represents the minimum performance standard required by federal regulation. Currently, 27 percent of tires are rated “A,” 59 percent are rated “B” and 14 percent are rated “C.” A tire’s ability to resist heat is an important safety factor. Tires that become overheated may fail.18 Jul 2004
What does a temperature mean on tires?
Temperature rating shows the tires’ ability to disperse heat build-up. Heat is what causes a tire to deteriorate over time. Therefore, a tire that has a high temperature rating will disperse heat better than one with a low temperature rating.
What does temperature rating 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 is a good treadwear rating?
Most tires used on passenger vehicles have a treadwear rating that falls between 200 and 500. Tires in this bracket offer a great mix of grip and safety, matched with enough longevity to last multiple years if not driven hard every day. Tires with medium treadwear are therefore excellent for everyday driving.9 Jul 2021
What does AA mean on tires?
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. Temperature (the heat resistance rating)
What does 400 AA mean on a tire?
What does UTQG 600 AA mean?
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 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 AA tire rating mean?
Temperature, the tire’s heat resistance, is stated in letters. A tire graded “A” is the highest, “B” is average and “C” the lowest. 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).18 Jul 2004
How many miles is a 600 treadwear rating?
That said, the most accurate indicator for how many miles a tire will last may be its mileage warranty. Unlike a treadwear grade, a warranty is the manufacturer putting their money where their mouth is. A tire rated 600 AA with a 70,000 mile warranty is quite likely to live up to it.
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.On the other end, today’s more durable tires carry UTQGUTQGThe temperature grades, from highest to lowest, are A, B and C.

Is a 500 treadwear rating good?
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. 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.6 Dec 2017
How long will a 280 treadwear tire last?
so 280 would be 20,160 miles.21 Mar 2006

What does a 300 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 100.17 Mar 2021
