15" Iroc wheel width?
As the title asks..Is the 15" Iroc 7 or 8 inches wide? Can only find info on the 16"ers.
Thanks!
BTW whats the widest I could go on that and still maintain maximum traction..255/55?

Re: 15" Iroc wheel width?
You couild go 255 55 on a 7"rim but I would go with a 8" rim and put on a 275 50. Otherwise go with a 235 60 on the 7". The 255 is only 0.5" wider.
