Understanding the 285/45R22 XL size

In the size code 285/45R22, 285 is the section width in millimetres (about 11.2"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 128.3 mm. R22 means radial construction on a 22-inch wheel, giving an approximate overall diameter of 32.1".

The load index 114 means each tire supports up to 2,601 lbs — about 10,404 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).

At $200.99 per tire, a full set of four costs $803.96. That is about 19% below the average price of the 99 tires we stock in this size. Backed by a 70,000-mile treadwear warranty, that works out to roughly $11.49 per 1,000 miles across the set.
