I am looking to buy some rims for my 94 EB and i am not sure what backspacing/ lugspacing etc i need to know about first. and the hub sticking through the rim....

5x4.5 bolt pattern. Stock rims are 15x7 and you want 3-4" backspacing. With 4x4 you'll need the front hubs to stick through, so find a rim that's got a big enough hole.

cool thank you huskyfan.

Keep in mind if you go wider like 15X8, 15X10 you need to lookout for the backspacing. Stock rims are 4.5" backspace. If you go with a 15X8, that's 1" less back space(3.5) you need to have the same clearence as stock. 15X10 you need 3"'s less back space(1.5") These are for a stock look. You can go more backspaceing say a 3.75" or 4" & that will make the wheel stick out a little past the fenders which most people like anyway. The most popular backspacing on 15X8 rims is 3.75". Also keep in mind the tire size you are running. You want to be able to fit the tire/rim combo on the X without rubbing issues. Do a seach on that there's a world of info on that subject.

i will be getting a set of rims off of a 97 limited. they are the "3 spoke chrome" ones. they are 5 lug 4.5 and i BELIEVE 3,75 backspacing. not sure but i will be getting 1 1/4" spacers in a few months anyways. simply to offset the top heavyness of the lift and larger tires.
