Understanding the 275/55R20 XL size

In the size code 275/55R20, 275 is the section width in millimetres (about 10.8"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 151.3 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 31.9".

The load index 117 means each tire supports up to 2,833 lbs — about 11,332 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 Toyo Open Country R/T is built for

The Toyo Open Country R/T is an all-season tire, balancing dry grip, wet traction and tread life across spring, summer and autumn conditions. It carries an M+S (mud and snow) marking for light winter service. It is classified for rugged-terrain (r/t) (m/t & r/t - mainly lt specific) use.

Tread life and grip ratings

This tire carries a UTQG rating of 500 A B. The treadwear grade of 500 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 $252.75 per tire, a full set of four costs $1011.00. That is about 25% above the average of the 156 tires we stock in this size, reflecting its position in the range. Backed by a 45,000-mile treadwear warranty, that works out to roughly $22.47 per 1,000 miles across the set.
