Understanding the 235/40ZR17 size

In the size code 235/40R17, 235 is the section width in millimetres (about 9.3"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 94 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 24.4".

The load index 90 means each tire supports up to 1,323 lbs — about 5,292 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 200 AA A. The treadwear grade of 200 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 $193.30 per tire, a full set of four costs $773.20. That is about 12% above the average of the 11 tires we stock in this size, reflecting its position in the range.
