If you do a search on tyre size, it's easily the most expensive. Conti Sport 5s and Pilot Sports 2s are £100 less, and probably better tyres for year round! I'd still buy winters though. Reminds me of when the M3 CSL came out and owners were horrified when they had zero grip in the wet.
The M3 CSL came with Michelin Pilot Sport Cups that are semi-slick, they were very obviously track tyres and would be horrible in the wet. The PZero Corsas (despite Corsa being Race in Italian
) seem to be more of a combination road and track tyre. Pirelli claim the wet performance is "Excellent". https://www.pirelli.com/tyres/en-gb/...corsa#/details
The problem seems to be the low temperature performance.
