2002 gmc sierra with a 3/4 belltech drop kit, bought the truck like this, still has stock 16" wheels with balloon tires it seems, I'll be two toning the truck in the spring once the car motor is finished, will be running 20" wheels, hopefully i can find some silver SS's that I can paint to go with two tone, I'm new to the truck scene, do not know whether to run 275/40 or 275/45 on these wheels, pics would be appreciated. bumpy roads up here, so need some sidewall.

 

If you want sidewall I have always loved the 265/50/20, good amount of sidewall and not too wide so you can tuck if you're dropped.

 

i run 305 40 20s with my 3-4 drop
