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 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.
Is UTQG 820 AB good?
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.
What does UTQG 800 AA mean?
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 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.
Which traction grade signifies the best traction?
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.
How do I read my UTQG rating?
The Course Monitoring Tire is assigned a grade and the test tire receives a grade indicating its relative treadwear. A grade of 100 would indicate that the tire tread would last as long as the test tire, 200 would indicate the tread would last twice as long, 300 would indicate three times as long, etc.
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 700 good?
Currently, the highest reported treadwear rating is 700. In fact, 98 percent of all tires tested ranked better than the control tire. 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 the purpose of a Sipe?
Siping reduces friction heat and its effect on your tire by allowing the tire to cool. The sipes act by isolating heat into small “corrals” and allowing air to pass between them, thereby dispersing the heat and naturally cooling the tire.
How many miles is a 800 treadwear rating?
Theoretically, a tire with a UTQG grade of 800 should last twice as long as one rated 400. 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.
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 speed rating is S?
Tire Speed Rating Chart Speed Rating Symbol Speed (mph) Speed (km/h) Q 100 mph 160 km/h R 106 mph 170 km/h S 112 mph 180 km/h T 118 mph 190 km/h.
Is a higher or lower UTQG better?
A system developed by the Department of Transportation, which helps consumers compare and rate tires on tread wear, traction, and temperature. Example: a tire with a UTQG of 400 AB. Therefore, a tire that has a high temperature rating will disperse heat better than one with a low temperature rating.
Which is better H or T rated tires?
A speed rating of T indicates that the tire can be safely driven up to 118 mph. A tire with an H rating has a higher limit — 130 mph — which means it can be safely driven faster than the tire with the 94T code.
What’s the best speed rating for tires?
Tires with a maximum speed capability higher than 300 km/h (186 mph), require a “ZR” in the size designation. Consult the tire manufacturer for maximum speed when there is no service description.Tire Speed Rating Chart. SPEED SYMBOLS Symbol Speed Speed (km/h) Speed (mph) A1 5 3 A2 10 6 A3 15 9.
What are three UTQG ratings?
The Uniform Tire Quality Grade system, AKA the UTQG tire rating system, is a system put in place by the National Highway Traffic Safety Administration (NHTSA). Its goal is to help you understand how your new tires will perform in three categories: treadwear, traction and temperature.
What does UTQG mean on a tire?
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.
How do you tell if tires are all season?
M+S stands for mud and snow, indicating that this is an all-season tire. It’s not the clearest of the specs, because there aren’t other designations for summer and winter tires: Summer tires simply lack the M+S, and winter tires are labeled M+S and add an icon of a mountain plastered with a giant snowflake.
How long will 200 treadwear last?
A tire rated at 200 has a projected tread life of 60,000 miles.
