The Pirelli Pzero is the original and first performance tyre that was named the Pzero. Thereafter a batch of others followed called the Pzero Roso?s and Nero?s. However, this is just the Pzero. The Pzero features an asymmetric tread design that is very similar to the Pzero Assimetrico don?t confuse the two, as they are both different. People often had bought the Assimetico when they really wanted these and vice versa. The Pzero has been around for some time and has won many accolades in the media for best performance tyre in various tyre tests. Our opinion it doesn?t disappoint the performance certainly gets it in the points, but it doesn?t get a medal from us. There are other makes including Pirelli tyres that are better. The grip levels are high in the wet and the dry. The only departments were the Pzero doesn?t fare as well is the tread wear and feedback sections but this could be because of individual driver preference and driving style rather than the tyre itself.
