    I currently have 33-12.5, 15's. Not sure what the rim width is. I am going to have to get some new tires soon. Don't have the bucks, or time right now to move up to larger diameter tires, and lift kits, etc... Although, can't wait to win the lottery! Lol, and buy a fully stocked garage to do all this work! Anyway, I am planning on going camping and such out at the Slab area around here. Considering its mostly sand, slabs of rock. I was thinking about going to 33-14.5, 15's. What is the ideal rim width for that size tire. I am hoping I can use my present ones. (Some guy named Murphy may have something to say about that!)

    Well it helps to know the rim size to know if that tire size will work... you really can't decide what tires until you know that...

    A general rule of thumb is 1" either way compared to the tread width not over all.
    Check these guys out they list the real dimensions of the tire.

    Well for sand you would want to go wide like 15x12s or even 15x14s that way you dont sink in the sand. As for rock climbing you want to stay narrow to protect the rim and the bead like a15x10. I would say all aroind go with a 15x12. Out here for rock crawling we use narrow rims. My buddy use 15x7s for his 55x12.50r15s. I use 15x8s for my 35x12.50r15s.
