Understanding the 275/35R20 XL size

In the size code 275/35R20, 275 is the section width in millimetres (about 10.8"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 96.3 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 27.6".

The load index 102 means each tire supports up to 1,874 lbs — about 7,496 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 500 AA 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 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 $248.24 per tire, a full set of four costs $992.96. That sits close to the average for the 80 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $19.86 per 1,000 miles across the set.
