The Pirelli P Zero is a luxury high-performance tire, reviews say. It has been used as original equipment on Ferraris, Lamborghinis and Porsches. However, the P Zero now lags behind newer summer performance tires in the most recent tests. For example, experts say the new Michelin Pilot Super Sport (*Est. $195) gets a better grip on wet and dry roads, plus it's quieter, more comfortable and comes with a 30,000-mile tread-wear warranty (the Pirelli has none).
ConsumerReports.org compares the Pirelli P Zero with 22 other ultra-high-performance summer tires in its most recent tests. TireRack.com also conducts expert tests, but it compares the P Zero against only three other tires. The National Highway Traffic Safety Administration posts official tread-wear, traction and heat-resistance scores for the Pirelli P Zero in its searchable database of tire ratings. Reviews of the P Zero at Autos.ca and Car and Driver are derived from demonstrations at a Pirelli press event.
ConsumerReports.org ranks the Pirelli P Zero alongside other ultra-high-performance summer tires in an easy-to-read chart. Testers judge how quiet and comfortable the tires are, and they also evaluate rolling resistance, tread life and performance on wet and dry roads.

2. Tire Rack
The Pirelli P Zero finishes last in this comparison test of four high-performance summer tires by staff at this retail site. Testers call it "an older but still capable tire that can't quite match the capability of newer tires."

The P Zero gets the highest possible ratings for traction and heat resistance in government-mandated tests, but its tread-wear score is low, as is expected for a high-performance summer tire.

Tester Tony Whitney evaluates the Pirelli P Zero as part of a Pirelli media event. He recommends the tires after zooming around a racetrack in exotic sports cars shod in P Zeros, but this review spends more time explaining the tires' design than it does on actual test results.

5. Car and Driver
Car and Driver's reviewer attends the same Pirelli press event as the Autos.ca reviewer, at the Dubai Autodrome in the United Arab Emirates. He comes to similar positive conclusions about the tire, although he admits that any "tiny tweaks" to the other tire brands in the test (such as the wrong air pressure) could have skewed his opinion.
