You will be fine running that tire. Your biggest concern is how well it will hold the bead when you air down.
BigMike made a statment a few weeks ago about the same topic. I can't find the thread but I think he said somthing like a good setup is a tire 4" wider than the rim and you will be at the best unless you run beadlock and then it alomost does not matter. Dont quote me on this because I can not remeber for sure.
BigMike, please feel fre to correct me.
