Is 400 a good treadwear rating?

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. … Temperature rating shows the tires’ ability to disperse heat build-up.

What treadwear number is good?

The standard is set so that a rating of 100 is equal to 30,000 miles. The actual rating is a percentage of 30,000 miles. 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.

How long will a 400 treadwear tire last?

There are three aspects: traction, treadwear, and temperature. The word “treadwear” and a three-digit number following, is what you should look for. The bigger the number is, the longer the used tires last, and the harder their rubber is. For example, treadwear 400 will mean every 1/32” wears every 8,000-10,000 miles.

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.

What does 600 AB mean for tires?

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.
