What does 500 aa a mean on tires
What does AA tire rating mean?
traction grade
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.
What does UTQG 300 AA A mean?
Uniform Tire Quality Grade (UTQG) Standards | Tire Rack
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 400 AA mean on a tire?
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.
Is UTQG 600 AB good?
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.
How many miles is a 540 treadwear rating?
Those Confusing & Contradictory Grades Treadwear Grades Compared to Stated Warranties
| Mileage Warranty | Brand Type | UTQG Rating |
|---|---|---|
| House | 640 | |
| 85,000 | Major | 540 |
| Major | 700 | |
| 100,000 | Major | 700 |
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.
What is a good treadwear number?
For enthusiasts, the best part of the treadwear spectrum is the lowest part. Tires with treadwear ratings of 350 or less tend to have some performance pretentions, but for serious drivers and competitive racers, the only tires they will ever consider have treadwear ratings of 200 or less.
Is a higher treadwear number better?
A. The bigger the number, the longer the tread life. For instance, a tire that has a treadwear number of 200 lasts twice as long as one that has a number of 100.
What does XL mean on a tire?
extra-load tires
Some vehicles are equipped with “XL” tires. It doesn’t mean that they’re extra large, but it does mean that they are extra-load tires. The load index on these tires is much higher than a standard-load tire, which is why it is important to replace an XL tire with another XL tire.
How long should a 500 treadwear tire last?
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.
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.
Is 800 treadwear good?
A tire with a treadwear rating of 800 should theoretically last about twice as long as a tire with a treadwear rating of 400. A longer life tire will be designed with a harder rubber compound to withstand wear better.
Is a 700 treadwear good?
Currently, the highest reported treadwear rating is 700. In fact, 98 percent of all tires tested ranked better than the control tire. Temperature, the tire’s heat resistance, is stated in letters. A tire graded “A” is the highest, “B” is average and “C” the lowest.
What UTQG means?
Uniform Tire Quality Grading
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.
Which tire rating provides the least traction?
The traction grades, from highest to lowest, are “AA,” “A,” “B,” and “C.” If a tire is designed for extra traction in mud and snow, you’ll also see the designation “M+S.” You should buy the best tire your budget allows and one that fits your driving needs, too.
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.
What is good tire tread depth?
The tire tread depth gauge measures in 32nds of an inch. Good tire tread depth will be 6/32 or deeper. If the depth is 4/32, you should start thinking of replacing your tires and getting new ones. 2/32 or less means that you should change your tires ASAP.
Do all season tires have a snowflake on them?
Most all-season tires do not qualify for the Mountain/Snowflake symbol because the tread rubber in all-season and summer tires become hard at temperatures below 40 F.
Do all season tires count as winter tires?
Many all-season tires do great in the rain and bare pavement year-round. While a set of all-season tires can offer some traction in light snow and the occasional winter storm, they’re not designed for deep snow, ice, and cold weather (when temperatures stay below ~45Âş F).
Are all season tires worth it?
All-season tires perform well in warm weather, but they may offer less grip than summer tires, sacrificing some steering, braking, and cornering capabilities. This trade off is necessary for all-season tires to be able to provide acceptable performance in light winter conditions and provide longer tread life.
What tires have 3 peak snowflakes?
WHERE TO BUY TIRES WITH THE THREE-PEAK MOUNTAIN SNOWFLAKE SYMBOL. 3PMSF tires can be found in any tire or auto shop. Discount Tire carries quite a few of them but a few very popular ones are the BFGoodrich All-Terrain T/A KO2, the Bridgestone Blizzak WS90 and the Michelin X-ICE XI3.
