Understanding the 285/50R20 size

In the size code 285/50R20, 285 is the section width in millimetres (about 11.2"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 142.5 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 31.2".

The load index 112 means each tire supports up to 2,469 lbs — about 9,876 lbs across a full set of four. The speed symbol V certifies the tire to 149 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 800 A A. The treadwear grade of 800 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 $220.49 per tire, a full set of four costs $881.96. That is about 12% above the average of the 22 tires we stock in this size, reflecting its position in the range. Backed by a 80,000-mile treadwear warranty, that works out to roughly $11.02 per 1,000 miles across the set.
