does everyone buy 5 instead of 4 because of spare wheel? and if you get a flat then do you put your 16" on with three 17" just until you get a new tire? cos if i buy new alloys i need to know if i should get 4 or five? but dont want to spend anymore than i have too. also looking at The superleggera on performance alloy website, what wheel size should i need? 17 X 7 or 17 X 8 and i dont want tolose any speed so i need lowprofile wider so as to improve grip but not deminish speed?
(sorry for such a boring post)
