Hello fellow zuki fans, I have put the 2.5 inch Cal kit in my GV and on their website they recommend 215/75/16 for tires. I have not been able to find anything in that zone. BF goodrich makes the TA in 215/70/16 or General makes the Grabber AT2 in a 215/70/16. My brother has the 235/70/16's on his GV and it rubs at full steering lock. I want to avoid trimming any body work so any suggestions? Thanks for your help.

215/70 is less than an inch smaller than 215/75 (if my highly scientific guesstimate is right), which equals a half inch or less of lost clearance.  My adivce would be to get the BFG T/A in 215/70R16, I think along the same lines as you, prefering a slightly smaller tire to a slightly too big tire.
