Understanding the 325/30ZR21 XL size
In the size code 325/30R21, 325 is the section width in millimetres (about 12.8"). 30 is the aspect ratio — the sidewall height is 30% of the width, or roughly 97.5 mm. R21 means radial construction on a 21-inch wheel, giving an approximate overall diameter of 28.7".
The load index 108 means each tire supports up to 2,205 lbs — about 8,820 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.
What the Pirelli Pzero R is built for
The Pirelli Pzero R is a summer tire, tuned for maximum dry and wet grip in warm conditions; it is not intended for near-freezing temperatures. Fitment category: Passenger Car.
Tread life and grip ratings
This tire carries a UTQG rating of 280 AA A. The treadwear grade of 280 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 $592.17 per tire, a full set of four costs $2368.68. That is about 29% above the average of the 31 tires we stock in this size, reflecting its position in the range.
