Understanding the 245/50R18 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 100 means each tire supports up to 1,764 lbs — about 7,056 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 $140.24 per tire, a full set of four costs $560.96. That is about 26% below the average price of the 63 tires we stock in this size. Backed by a 55,000-mile treadwear warranty, that works out to roughly $10.20 per 1,000 miles across the set.
