They are a popular tyre for some reason. Nearly every car I have bought has come with Pirelli Pzero Rosso tyres which have been noisy and poor in the wet. The tyres on my SL are Bridgestones which are even worse! I cant wait to wear them out.
20-30 years ago, Pirelli were one of the best tyres available but as others have said, things have changed and they live on history. Accepting that they probably make some brilliant bespoke tyres for new supercars, they seem to have forgotten about the mass market and how expectations have grown.
I have ordered the Goodyear 5s so that is a remap, My Genius, new tyres booked in for and the diff to follow!
