Understanding the 285/30R20 XL size

In the size code 285/30R20, 285 is the section width in millimetres (about 11.2"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 85.5 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 26.7".

The load index 99 means each tire supports up to 1,709 lbs — about 6,836 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.

Price and value

At $257.24 per tire, a full set of four costs $1028.96. That is about 16% below the average price of the 59 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $20.58 per 1,000 miles across the set.
