Please Help Someone!!!!!!!

ok im new to trucks/rims, and my tire size is 31x10.5 R15 -6x137.9 BFG A/T

I am looking for a rim to with backspacing so the tire pops out a bit.HELP



I want to know what possible sizes I can use for rims from a minimum width of tire, to max. Ex. Can i fit a 10 in width rim on my 10.50 tire? or even higher in width, to what max?

I am looking for black 15" rims to fit the tires I already have, can anyone give me a specific link to a site.

Thanks in advance.:comphead:
