I just bought I 5'' trailmaster suspension lift for my 99 4dr 4wd Blazer. Having a hard time in figuring out what size wheels and tires I can get away with without having to mod it. Currently I have the 15x8 factory wheels with BFGoodrich 31x9.50 without any rubbing. I think I could get away with 33'' and factory spec wheels. But I am not sure bout the back spacing. Any help guys?

and oh yeah, I am a newbie to this as well.
