I've used 255/35/18 on the front with a 30 offset and it fits. (Hankook RS-3) I was polishing the screws that the clips use to hold the outside of the fender liner in place so I rolled the fenders a little. I'd say there was a credit card of clearance to the suspension bolt so I filed it for safety but I don't think it was necessary. I was at -2.4º negative camber and if you have less the fender might be more of a problem. I doubt a 255 Hoosier would fit.
