Tread life and grip ratings

This tire carries a UTQG rating of 40 C A. The treadwear grade of 40 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 C 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).

Price and value

At $418.19 per tire, a full set of four costs $1672.76. That sits close to the average for the 8 tires we stock in this size.
