I'm looking at having some custom drag wheels made for my newly acquired 1999 Silverado….I want to do 15x4 up front and 15x10 in the rear, but I have no idea what guys are running on backspacing. Please advise and if possible post a pic of your truck with the specific sizing/specs. Thanks!



(Sorry if this is the wrong section….I didn't see a wheel specific section)

 

Most run a 6.5-7" backspacing. So the smaller the number the more it is pushed out from under the truck.

Mine is a narrowed rear end 3" each side. 15x10" 4" backspacing. Pretty big and wide rear tire.
