Understanding the 315/30ZR20 size
In the size code 315/30R20, 315 is the section width in millimetres (about 12.4"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 94.5 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 27.4".
The load index 101 means each tire supports up to 1,819 lbs — about 7,276 lbs across a full set of four. The speed symbol Y certifies the tire to 186 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 100 AA A. The treadwear grade of 100 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 AA 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 $474.75 per tire, a full set of four costs $1899.00. That sits close to the average for the 12 tires we stock in this size.
