Understanding the P275/65R18 size
In the size code 275/65R18, 275 is the section width in millimetres (about 10.8"). 65 is the aspect ratio — the sidewall height is 65% of the width, or roughly 178.8 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 32.1".
The load index 114 means each tire supports up to 2,601 lbs — about 10,404 lbs across a full set of four. The speed symbol T certifies the tire to 118 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 $137.99 per tire, a full set of four costs $551.96. That is about 35% below the average price of the 185 tires we stock in this size. Backed by a 60,000-mile treadwear warranty, that works out to roughly $9.20 per 1,000 miles across the set.
