Understanding the 245/50R18 XL size

In the size code 245/50R18, 245 is the section width in millimetres (about 9.6"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 122.5 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 27.6".

The load index 104 means each tire supports up to 1,984 lbs — about 7,936 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).

Price and value

At $247.46 per tire, a full set of four costs $989.84. That is about 31% above the average of the 63 tires we stock in this size, reflecting its position in the range.
