Pirelli P Zero

1. ConsumerReports.org

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."

3. SaferCar.gov

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.

4. Autos.ca

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.
