Is 640 a good treadwear rating?
Here’s what’s important: The higher the tread wear grade, the longer a tire will last—according to the company that made the tire. 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.
How many miles is a 560 treadwear rating?
Some scores from the tests followed the tire makers’ claims fairly closely. 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.
What is SVC DESC?
A service description identifies the tire’s load index and speed rating. “Using a P195/60R15 87S tire size as our example, the 87S at the end of the size represents the tire’s service description. A service description identifies the tire’s load index and speed rating.”
What is a good Utqg 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 does traction AA mean 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).
What is tire speed rating H?
If you recall from earlier, the “H” speed rating doesn’t appear after “G” but between “U” and “V.” It represents a maximum speed of 130 mph (210 kph) and is commonly found on sports sedans and coupes.
What does 600 treadwear mean on a tire?
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, what does the treadwear number mean? Treadwear grades are an indication of a tire’s relative wear rate.
What does a 500 tread wear rating 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. 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 is the difference between the control tire and treadwear grade?
The control tire has a treadwear grade of 100. So, if the tire being tested gets a 200 treadwear rating, that means it’s expected to take twice as long to wear out as the control tire. To get a treadwear grade, tires run a 640-kilometre course for 11,520 km, with tread depths being measured every 1,280 to give a projected tread life.
What is the difference between treadwear and traction grade?
To get a treadwear grade, tires run a 640-kilometre course for 11,520 km, with tread depths being measured every 1,280 to give a projected tread life. A traction grade tells you how well your tire can stop in wet conditions.
