Understanding the 245/45R17 XL 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 99 means each tire supports up to 1,709 lbs — about 6,836 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 500 A A. The treadwear grade of 500 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 A 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 $111.74 per tire, a full set of four costs $446.96. That is about 24% below the average price of the 79 tires we stock in this size. Backed by a 55,000-mile treadwear warranty, that works out to roughly $8.13 per 1,000 miles across the set.
