Understanding the 245/30ZR20 XL size
In the size code 245/30R20, 245 is the section width in millimetres (about 9.6"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 73.5 mm. R20 means radial construction on a 20-inch wheel, giving an approximate overall diameter of 25.8".
The load index 90 means each tire supports up to 1,323 lbs — about 5,292 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 320 AA A. The treadwear grade of 320 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 $152.99 per tire, a full set of four costs $611.96. That is about 44% below the average price of the 29 tires we stock in this size.
