This is the info from a Chevy data sheet. I'm gonna assume that a 1/2 GMC used the same. Mine is a Burb but they put them on 115" PU frames.
Tires: Five tubeless 6.70-15/4PR
Wheels: five 15” x 5.0”; attachment, 6 studs on 5 1/2” circle.
Anyone know what the back spacing was on stock rims and did they have the bumps for the hubcaps?
Thanks
