15x4 & 15x7 stock steelies?

Sweet thanks for the insight.

Made a makeshift measuring "device" before I headed out there so I could measure em a bit better then eyeballing it, or scrapping crap off the rims to read the markings.Simple 15.5" pieces of wood to set against the rims bead on both sides to measure width.Then set one piece at the back and measure the backspacing.Looked like simian football while I was measureing them, but got it done :)

i had to rework my post , i forgot a couple pics lol. thats a great idea. some folks make the mistake of measuring the backspace by the wheel lip and not the center hub face. because the dippys 15 x7 has a flare they assume it is a 6.5 wheel, when actually it is a 15 x 7. i think the dippys and ave's (or passenger car 15 x 7) are the only wheel to have this type of flare , and the 6 1/2 and 6 " do not have it. so i think its safe to say if you see this "flare" , plus the holes for a centercap, they are all 15 x 7
