Understanding the 235/45ZR17 XL size

In the size code 235/45R17, 235 is the section width in millimetres (about 9.3"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 105.8 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 25.3".

The load index 97 means each tire supports up to 1,609 lbs — about 6,436 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.

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 $96.74 per tire, a full set of four costs $386.96. That is about 29% below the average price of the 85 tires we stock in this size.
