About the Pirelli P4 Persist AS Plus

Understanding the 215/55R17 size

In the size code 215/55R17, 215 is the section width in millimetres (about 8.5"). 55 is the aspect ratio — the sidewall height is 55% of the width, or roughly 118.3 mm. R17 means radial construction on a 17-inch wheel, giving an approximate overall diameter of 26.3".

The load index 94 means each tire supports up to 1,477 lbs — about 5,908 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 820 A A. The treadwear grade of 820 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 $135.00 per tire, a full set of four costs $540.00. That is about 8% above the average of the 139 tires we stock in this size, reflecting its position in the range. Backed by a 85,000-mile treadwear warranty, that works out to roughly $6.35 per 1,000 miles across the set.
