Probably been done already but reading comments on the BBS about Bridgestone S03 etc i'm swaying towards Toyo's or Goodyear F1's to go on a P1 as 215/40 R17. Once tried F1's on my old Catalunya and wasnt that impressed. Does the larger tyre make any difference. I'm interested in the Toyo / Goodyear comparison cos they have effectively the same tread pattern
