I read here that 235/50/18 should fit ok. I am looking at the Falken Wildpeaks, and notice that they are listed at 28 lbs for the 215/55 and 32 for the 235/50. Both are listed at 27.3 OD.

Weight difference and less likelyhood of rubbing issues has me leaning towards the 215/55/18.

Any have thoughts I might be missing between the two?
