Understanding the 255/35ZR20 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 93 means each tire supports up to 1,433 lbs — about 5,732 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 40 C A. The treadwear grade of 40 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 C 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 $337.38 per tire, a full set of four costs $1349.52. That is about 53% above the average of the 82 tires we stock in this size, reflecting its position in the range.
