hey just wonndering if there is a way to correct the speedo if u whack a set of mags on ya car?

17's wouldent throw it out much would they because a higher profile tyre like the 1 on the stock mags should only be as big as a 17" mag with a low profile right?

Might have to take it to a mechanic so they can recalibrate the speedo.

provided you get tyre size correct it wont affect it at all

so 17 inch should be 215/40r17 to keep exact rolling diameter as original size wheels/tyres and 18 inch should be 225/35r18

heres a handy site for you its called 1010tyres has a calculator to work it all out
