I currently have a 6" procomp suspension lift kit runnin 35's. What size tires do yall think i should run if I add 3" of body? I also want to keep my tires 12.50" wide.

 

why 12.5 wide?
37/13.5 would look sick or mayb even 38s

 

TonkaTruck had a 6 inch pro comp and 3 inch body and was running, 38's. if it was my truck id run bilsteins up front gain an extra 2 inches, add-a-leaf in the back, and get some 37's.

 

I'd go with 37's.

 

I believe TonkaTruck is also running the bilsteins and he fit 38x15.5

I think a 12.5 would look to thin with that big of lift.

 

What are the advantages of running 37's instead of getting the 3" body and running 38's? And i also meant i want my tires 13.50" wide. Also, what size gears would yall go with?

 

4:88

 

4.88's with anything over 35's

IMO the only advantage would be that the 37 would be somewhat lighter because I believe most of the 38's come in 15.5. Also with the body lift you would have to relocate your hitch and muffler.
