Ok, so I am thinking of getting some rims for the 9. I want to get some Volks but don't see the justification at $1200ish per wheel for the 9. If it's a Cayenne, Q7, and etc, yes. So this brings me to the marketplaces on various forums like the Z and Infiniti G. Can i get away with a staggered set up? Thinking of 20x8.5/9 front and 20x10/10.5 in the rear and do a 265/45 up front and 285/40 in the rear? Overall diameter should be very close. Any issues with the AWD system like excessive differential wear and etc.?
