As said by Fastdmr, at 70% turn with 285/75 its hitting plastic, but once it passes the 70% mark, then the rest is fine. Height does not seem to be the issue. Its width that may be the problem. Do 33s fit....sure they do.....but the real question is how wide can you go. After taking measurements, i think if u go 12.50 wide, your hitting sheet metal. But then again, you dont know until you test fit.
