Understanding the 285/40ZR17 XL size
In the size code 285/40R17, 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. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 26".
The load index 104 means each tire supports up to 1,984 lbs — about 7,936 lbs across a full set of four. The speed symbol W certifies the tire to 168 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 320 AA A. The treadwear grade of 320 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).

At $177.75 per tire, a full set of four costs $711.00. That is about 12% below the average price of the 2 tires we stock in this size.
