Understanding the 245/45ZR17 size

In the size code 245/45R17, 245 is the section width in millimetres (about 9.6"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 110.3 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 25.7".

The load index 95 means each tire supports up to 1,521 lbs — about 6,084 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 $182.60 per tire, a full set of four costs $730.40. That is about 25% above the average of the 79 tires we stock in this size, reflecting its position in the range.
