Understanding the 315/40ZR21 XL size

In the size code 315/40R21, 315 is the section width in millimetres (about 12.4"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 126 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 30.9".

The load index 115 means each tire supports up to 2,679 lbs — about 10,716 lbs across a full set of four. The speed symbol Y certifies the tire to 186 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 300 AA A. The treadwear grade of 300 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 AA 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 $360.74 per tire, a full set of four costs $1442.96. That is about 13% below the average price of the 29 tires we stock in this size. Backed by a 20,000-mile treadwear warranty, that works out to roughly $72.15 per 1,000 miles across the set.
