Local 4wheelparts store has a special on BFG's right now, buy 4 and get instant 100 off. So I am going to get a set of 33's for my lift in march (their sale ends at end of february). Now my question is the rims, what is the big difference between 15x8 and 15x10? They have black rock crawler rims 15x8 40 and the 15x10 I think were 60 each. I will probably go with the 15x8 but just wanted to make sure I wasn't missing out on the 15x10 thing. lol

15x8, 3.75" backspacing is what I recommend.

The 15x10 will make rubbing more likely to occur. Also, it makes the width for which the bead mounts on wider which makes the bead not as firmly mounted.

i have 31x10.5 pro comp m/t will they fit my 15x10 rock crawler wheels?
