Understanding the 245/35R18 XL size

In the size code 245/35R18, 245 is the section width in millimetres (about 9.6"). 35 is the aspect ratio — the sidewall height is 35% of the width, or roughly 85.8 mm. R18 means radial construction on a 18-inch wheel, giving an approximate overall diameter of 24.8".

The load index 92 means each tire supports up to 1,389 lbs — about 5,556 lbs across a full set of four. The speed symbol Y certifies the tire to 186 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 $177.74 per tire, a full set of four costs $710.96. That sits close to the average for the 31 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $14.22 per 1,000 miles across the set.
