Understanding the 255/40R19 XL size
In the size code 255/40R19, 255 is the section width in millimetres (about 10"). 40 is the aspect ratio — the sidewall height is 40% of the width, or roughly 102 mm. R19 means radial construction on a 19-inch wheel, giving an approximate overall diameter of 27".
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 540 A A. The treadwear grade of 540 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 $154.49 per tire, a full set of four costs $617.96. That is about 28% below the average price of the 89 tires we stock in this size. Backed by a 45,000-mile treadwear warranty, that works out to roughly $13.73 per 1,000 miles across the set.
