The load index 98 means each tire supports up to 1,653 lbs — about 6,612 lbs across a full set of four. The speed symbol W certifies the tire to 168 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.
Tread life and grip ratings
This tire carries a UTQG rating of 200 A A. The treadwear grade of 200 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 $309.00 per tire, a full set of four costs $1236.00. That is about 12% below the average price of the 7 tires we stock in this size.
