Yeah,I was looking around on Tire Rack's site and it seems that they just list tire/wheel upgrade sizes,that are closest to the vehicles factory diameter. Would the 15mm offset be a problem on a VX? I noticed on here that some members where running 285/60/18's on there VX's.Are those on VX's that are lifted or stock suspended.When I check sizes on a tire calculator it seems that 295/50/20's are extremely close to that diameter.Thanks for your help.
