The Pirelli Pzero Rosso is a max performance tyre that is part of the Pzero group. Pzero is a group of ultra performance tyres namely the Rosso, Nero, and Assimetrico. The Rosso pattern is asymmetric meaning the inside and outside designs are different. Our opinion the Rosso has been around for a long time it?s time Pirelli upgraded this they have created the P7 Cinturato. The Rosso gets some really good reviews wet and dry grip are top. The Rosso does notably do better in dry weather than in the rain, and for some the tyre wears really well.
