Understanding the 315/35ZRF21 size

In the size code 315/35R21, 315 is the section width in millimetres (about 12.4"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 110.3 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 29.7".

The load index 107 means each tire supports up to 2,149 lbs — about 8,596 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 240 AA A. The treadwear grade of 240 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 $486.74 per tire, a full set of four costs $1946.96. That is about 18% above the average of the 26 tires we stock in this size, reflecting its position in the range.
