Understanding the 235/75R15 XL size

In the size code 235/75R15, 235 is the section width in millimetres (about 9.3"). 75 is the aspect ratio — the sidewall height is 75% of the width, or roughly 176.3 mm. R15 means radial construction on a 15-inch wheel, giving an approximate overall diameter of 28.9".

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 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.

What the Sumitomo Encounter AT is built for

It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test.

Tread life and grip ratings

This tire carries a UTQG rating of 660 A B. The treadwear grade of 660 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 $113.99 per tire, a full set of four costs $455.96. That sits close to the average for the 73 tires we stock in this size. Backed by a 60,000-mile treadwear warranty, that works out to roughly $7.60 per 1,000 miles across the set.
