Understanding the 255/35ZR20 XL size

In the size code 255/35R20, 255 is the section width in millimetres (about 10"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 89.3 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 27".

The load index 97 means each tire supports up to 1,609 lbs — about 6,436 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 320 AA A. The treadwear grade of 320 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).

At $151.50 per tire, a full set of four costs $606.00. That is about 31% below the average price of the 82 tires we stock in this size.
