Understanding the 275/40ZR17 XL size

In the size code 275/40R17, 275 is the section width in millimetres (about 10.8"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 110 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 25.7".

The load index 102 means each tire supports up to 1,874 lbs — about 7,496 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).

Price and value

At $157.50 per tire, a full set of four costs $630.00. That is about 13% below the average price of the 30 tires we stock in this size.
