Ivan Stewart Rims/Tire Size?
 

I have a 2002 4Runner Sport Edition 4x4 and have recently purchased the Ivan Stewart TRD rims (16x8s) and am wondering what is the largest tire I can put on them without lifting my 4Runner. I currently have 265/70/16s on them now, but heard that I can go up to 265/75/16s. Anyone have any idea on what is the largest size I can go up to without the tire rubbing?
