Understanding the 255/40ZR20 size

In the size code 255/40R20, 255 is the section width in millimetres (about 10"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 102 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 28".

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 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 100 AA A. The treadwear grade of 100 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 $366.75 per tire, a full set of four costs $1467.00. That is about 34% above the average of the 93 tires we stock in this size, reflecting its position in the range.
