he is right on 17's yes cause we have run them on a 95 here on thailand,its all about front clearance tho 18's are not forgiving on width as 17 inch rims are, but as for rubbing yes, we have done sumthing called "rolling" the inner fender well to help assure the inner lip of the fender well will not ruin the outer part of the tire in extreme situations.i honestllu would 225 in front, maybe 235 if yud like and surelly 235 in rear
