Understanding the 245/70R17 size

In the size code 245/70R17, 245 is the section width in millimetres (about 9.6"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 171.5 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 30.5".

The load index 110 means each tire supports up to 2,337 lbs — about 9,348 lbs across a full set of four. The speed symbol S certifies the tire to 112 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 Nexen Roadian AT PRO RA8 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 560 A B. The treadwear grade of 560 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 $143.25 per tire, a full set of four costs $573.00. That is about 14% below the average price of the 126 tires we stock in this size. Backed by a 50,000-mile treadwear warranty, that works out to roughly $11.46 per 1,000 miles across the set.
