new to this whole forum thing and i was wondering if anyone can point me in the right direction. so i have an idea of what i want on my truck but dont really know too much about the subject. I have an 08 gmc sierra stealth grey extended cab and for starters i want either a leveling kit or a 4 inch lift. 20 or 18 inch rims with decent -offset that will poke out a bit. lastly i see guys with like 22s and 24s stretching their tires. are there any dimensions on off road tires that will give me that look on 20s? if anyone has pictures with dimensions i would really appreciate the help.
