About the Pirelli P4 Persist AS Plus

Understanding the 185/65R15 size

In the size code 185/65R15, 185 is the section width in millimetres (about 7.3"). 65 is the aspect ratio — the sidewall height is 65% of the width, or roughly 120.3 mm. R15 means radial construction on a 15-inch wheel, giving an approximate overall diameter of 24.5".

The load index 88 means each tire supports up to 1,235 lbs — about 4,940 lbs across a full set of four. The speed symbol T certifies the tire to 118 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 $107.60 per tire, a full set of four costs $430.40. That is about 26% above the average of the 59 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 $5.06 per 1,000 miles across the set.
