Understanding the 275/45R21 XL size

In the size code 275/45R21, 275 is the section width in millimetres (about 10.8"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 123.8 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 30.7".

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 H certifies the tire to 130 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 Nokian Outpost APT is built for

The Nokian Outpost APT is an all-weather tire — a year-round option certified for severe snow service, so it can stay on the vehicle through winter. It carries the three-peak mountain snowflake (3PMSF) symbol, meaning it passed a standardised severe-snow traction test. It is classified for all-terrain (a/t) use.

Tread life and grip ratings

This tire carries a UTQG rating of 700 A A. The treadwear grade of 700 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 A reflects heat resistance at sustained speed (A is highest).

Price and value

At $287.63 per tire, a full set of four costs $1150.52. That sits close to the average for the 73 tires we stock in this size. Backed by a 65,000-mile treadwear warranty, that works out to roughly $17.70 per 1,000 miles across the set.
