Benefits

* Provides a quiet and smooth highway ride* Help clear mud and maintain traction* To provide biting edges for traction* Strengthens the block edge to reduce irregular wear* Adds rigidity to tread blocks to reduce flex* Protects the bottom of groove from stone drilling* Provides traction in off-road environments* Provides additional biting edges for more traction

Understanding the 285/70R17 size

In the size code 285/70R17, 285 is the section width in millimetres (about 11.2"). 70 is the aspect ratio — the sidewall height is 70% of the width, or roughly 199.5 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 32.7".

The load index 116 means each tire supports up to 2,756 lbs — about 11,024 lbs across a full set of four. The speed symbol Q certifies the tire to 99 mph under its rated load. Always match or exceed the load index and speed rating listed on your vehicle's door-jamb placard.

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 $222.75 per tire, a full set of four costs $891.00. That sits close to the average for the 135 tires we stock in this size.
