This was all absolutely fantastic advice, thank you I really do appreciate it, I feel like I am settling on the Michelin Pilot Sport 4S after reading all of the advice Now the next question I have is what are the recommended tyre sizes people have settled on after years of knowledge and experience? There is so much info out there it's hard to know what is current, ideal or even correct... I have a 370z GT so nothing too wild or different such as a Nismo etc, but it's currently fitted with 245/40 on the front and R19275/35 R19 on the rear... thank you for the help as always!
