What the Toyo Extensa HP II is built for

Tread life and grip ratings
This tire carries a UTQG rating of 500 A A. The treadwear grade of 500 is a relative durability score — a grade of 200 is expected to last roughly twice as long as a grade of 100 under the same controlled test. Traction grade A measures straight-line wet stopping grip (AA is highest, then A, B and C). Temperature grade A reflects heat resistance at sustained speed (A is highest).

At $152.69 per tire, a full set of four costs $610.76. That is about 31% below the average price of the 10 tires we stock in this size. Backed by a 45,000-mile treadwear warranty, that works out to roughly $13.57 per 1,000 miles across the set.
