I'm looking at Axis Maglites for my S40. I'd like to go 17x7 for the wheel, but I'm not sure what size rubber to go for. Wheelmax.com offers a package with 205/40's (http://www.wheelmax.com/Wheels/Axis/axis.htm), but I think I might want some more rim protection. Is going wider going to give me problems? If I do bump up to 215, would I have to run a 45 series tire to fit? Thanks for whatever help you can offer!
