Understanding the 255/50R20 size

In the size code 255/50R20, 255 is the section width in millimetres (about 10"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 127.5 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 30".

The load index 109 means each tire supports up to 2,271 lbs — about 9,084 lbs across a full set of four. The speed symbol H certifies the tire to 130 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 600 A A. The treadwear grade of 600 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 A 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 $149.24 per tire, a full set of four costs $596.96. That is about 27% below the average price of the 121 tires we stock in this size. Backed by a 65,000-mile treadwear warranty, that works out to roughly $9.18 per 1,000 miles across the set.
