Understanding the 245/60R20 size

In the size code 245/60R20, 245 is the section width in millimetres (about 9.6"). 60 is the aspect ratio — the sidewall height is 60% of the width, or roughly 147 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 31.6".

The load index 107 means each tire supports up to 2,149 lbs — about 8,596 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 740 A A. The treadwear grade of 740 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 $182.99 per tire, a full set of four costs $731.96. That sits close to the average for the 28 tires we stock in this size. Backed by a 70,000-mile treadwear warranty, that works out to roughly $10.46 per 1,000 miles across the set.
