hey guys, I have a 95 1500 stepside and i just purchased rims(15x10) with a b.s. of about 4", what do i need to fit 33x11.5x15 or 33x12.5x15? i'm thinking i'm going to need a 4" lift or will a 2"-3" lift be enough?

 

Does someone have a chart or something that we can post as a sticky, because I swear this is a pretty dern common question
