I have a 1996 Tahoe, 4d/4WD, with a 2" body lift and have not gotten a definative answer from anyone about the maximum size tire that will fit on my 16x9 rims (with 4.25" backspace)...The closest guess is a 285/75-16. I am looking at the Nitto Terra Grappler. I prefer not to make mods....but need an education from someones experience. Please help if you can. Thanks!
