Understanding the 285/45R22 size
In the size code 285/45R22, 285 is the section width in millimetres (about 11.2"). 45 is the aspect ratio — the sidewall height is 45% of the width, or roughly 128.3 mm. R22 means radial construction on a 22-inch wheel, giving an approximate overall diameter of 32.1".
The load index 114 means each tire supports up to 2,601 lbs — about 10,404 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 Cooper Discoverer Rugged Trek is built for
The Cooper Discoverer Rugged Trek 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 mud-terrain (m/t) use.
Tread life and grip ratings
This tire carries a UTQG rating of 600 A B. The treadwear grade of 600 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 $317.99 per tire, a full set of four costs $1271.96. That is about 28% above the average of the 99 tires we stock in this size, reflecting its position in the range. Backed by a 60,000-mile treadwear warranty, that works out to roughly $21.20 per 1,000 miles across the set.
