Ok here's one for you.
I have a 2009 NISMO with 10.5" rear rims. From what I've read here a 305-30-19 would be the largest tire for this wheel.
However a friend (self proclaimed expert) says "ah you can put a 325-30-19 on that wheel, I've seen it done all the time and those manufacturers min/max rim sizes are just guide lines."
Please help me with this guy. If it does fit which it doubt it's going to be totally unsafe or look like crap. I'm not sure I would even want to go with the 305, the 285 seems about right to me.
Thanks for any help.
