Understanding the LT275/70R18 E size

In the size code 275/70R18, 275 is the section width in millimetres (about 10.8"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 192.5 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 33.2".

The load index 125 means each tire supports up to 3,638 lbs — about 14,552 lbs across a full set of four. The speed symbol R certifies the tire to 106 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

Price and value

At $239.25 per tire, a full set of four costs $957.00. That sits close to the average for the 105 tires we stock in this size. Backed by a 40,000-mile treadwear warranty, that works out to roughly $23.93 per 1,000 miles across the set.
