Understanding the 285/40ZR20 XL size

In the size code 285/40R20, 285 is the section width in millimetres (about 11.2"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 114 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 29".

The load index 108 means each tire supports up to 2,205 lbs — about 8,820 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.

What the Hankook Dynapro EVO AS RA21 is built for

The Hankook Dynapro EVO AS RA21 is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. It carries an M+S (mud and snow) marking for light winter service. Fitment category: Passenger Car, SUV/CUV, Performance, UHP.

Tread life and grip ratings

This tire carries a UTQG rating of 540 AA A. The treadwear grade of 540 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 AA 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 $208.49 per tire, a full set of four costs $833.96. That is about 40% below the average price of the 29 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $16.68 per 1,000 miles across the set.
