Understanding the 215/50RF17 XL size

In the size code 215/50R17, 215 is the section width in millimetres (about 8.5"). 50 is the aspect ratio — the sidewall height is 50% of the width, or roughly 107.5 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 25.5".

The load index 95 means each tire supports up to 1,521 lbs — about 6,084 lbs across a full set of four. The speed symbol V certifies the tire to 149 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 640 A A. The treadwear grade of 640 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 A reflects heat resistance at sustained speed (A is highest).

Price and value

At $188.99 per tire, a full set of four costs $755.96. That is about 51% above the average of the 106 tires we stock in this size, reflecting its position in the range. Backed by a 65,000-mile treadwear warranty, that works out to roughly $11.63 per 1,000 miles across the set.
