Excuse the innuendo in the title, but didn't know how else to word it ?

Basically, how wide & big do people run aftermarket wheels on their 1.9 Multijet Sporting Grande Punto's? Obviously they come with 17's but I want to change to a more aggressive wheel, but just wondering on what widths would fit without arch work & what size people recommend?

this should help you !

i can't post the URL but search "rimstock" then click on "fitment guide"
biggest (but may have issue with arch depending on ET and lowering amount ) 7.5 x 18 215/35R18 205/40R18

thanks,
