What does 500 treadwear mean on a 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. 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 a good treadwear grade?
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. Traction and temperature scores: Those scores denote a tire’s wet-stopping ability and temperature resistance. For traction, AA is best, C is worst.
What does treadwear 520 mean on a tire?
If a tire is rated 100, it is expected to last as long as the test tire. In the above example, the treadwear rating is 520, so a tire tech may estimate the tread life of that tire at around 52,000 miles.
How many miles is a 500 treadwear rating?
Over 500 = approximately 80,000 miles. 5. Traction – Traction, from high to low, is AA, A, B, C. This rating indicates the tire’s ability to stop on wet roads, measured under controlled conditions.
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.
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.
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 tire has the highest treadwear rating?
The longest lasting tires in Consumer Reports’ tests are the Pirelli P4 Four Seasons Plus. They claim 90,000 miles, and Consumer Reports estimates they’ll go 100,000. Consumer Reports says don’t expect to get all your money back if your tires wear out before the mileage warranty.
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.
How many miles are tires good for?
As a general rule, the original tires on a new vehicle or quality replacement tires should last up to 50,000 miles. However, many factors will have a significant impact on any tire’s life and may substantially shorten its life expectancy.
How long will 200 treadwear last?
A tire rated at 200 has a projected tread life of 60,000 miles. A tire rated at 50 has a projected tread life of 15,000 miles.
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.
Why do new car tires wear out so fast?
The OEM tires that came with your car can’t be replaced (which is a good thing) after they’ve worn out. And they will wear out much sooner than they should. This is because virtually all auto manufacturers specify very soft rubber which means they wear out too fast.
How do you tell if a tire is all season?
You may see all-season tires with “M+S” marked on the sidewall. This stands for “mud and snow” and means that the tire has performed well in packed snow and mud. It does not mean the tire has the same traction in the cold or on ice as a proper winter tire.
