I'm looking into getting new wheels for my 2008 GX470 and thinking about putting on OEM GX460 18-inch wheels. Based on my research, there is a 27mm difference in the offset (GX470 is 25MM and GX460 is 52MM). My question is will this cause any issues? What needs to be done to correct this when the new tires are put on my GX 470? Will if effect the performance of my GX470? I need to get tires ASAP so your quick responses are appreciated. Thank you.
