Can anyone give me a bit of advice, I need some new rear tyres and I want to get Michelin pilot super sports, the tyres on at the mo are pilot sports (not super sports) it says on the tyres.... 245/45 ZR 18, 96Y. Could anyone tell me the equivalent for the super sports, am I right thinking it would be 245/45 R 18, 100Y, that they have listed on Camskills site?
