Understanding the 255/70R17 size

In the size code 255/70R17, 255 is the section width in millimetres (about 10"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 178.5 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 31.1".

The load index 112 means each tire supports up to 2,469 lbs — about 9,876 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 $147.74 per tire, a full set of four costs $590.96. That is about 11% below the average price of the 55 tires we stock in this size. Backed by a 60,000-mile treadwear warranty, that works out to roughly $9.85 per 1,000 miles across the set.
