I run bigger with no probs
I have a set of 305/70/16 Wrangler MT/R's, I ran these for a year on my stock 7" rims with no problem, I then bought a set of 10" rims a few months ago and I still using the same set of tires, as far as tire wear goes, anybody that uses MT/R's can tell you they are not the best highway tire as far as wearing goes, but I got roughly 60 000kms out of mine on the 7" rim, and they still wore perfect when I switched to 10"
