Understanding the 255/55R18 XL size
In the size code 255/55R18, 255 is the section width in millimetres (about 10"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 140.3 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 29".
The load index 109 means each tire supports up to 2,271 lbs — about 9,084 lbs across a full set of four. The speed symbol H certifies the tire to 130 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 600 A B. The treadwear grade of 600 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 B reflects heat resistance at sustained speed (A is highest).
Price and value
At $158.25 per tire, a full set of four costs $633.00. That is about 16% below the average price of the 83 tires we stock in this size. Backed by a 65,000-mile treadwear warranty, that works out to roughly $9.74 per 1,000 miles across the set.
