Rim back spacing?
 

Stock 12bolt under 71 LWB with Drum brakes.
what BS will work?

Will a Weld ProStar 15x10 7.5BS with a 275/60/15 Hoosier DR work?

I probably will have to get an adaptor since i have 5x5 and the rims are 5x4.75.

I want to see what the truck will do with the 6.0 in it and I know the street tires have no chance....truck is not set up to DR that is for sure so it should be hilarious!!!

My truck is a 82, so it might be different. I used a 15X10 with 4.5BS and it put the tire just inside the fender lip and left me several inches on the inside of the tire. I would think 7.5BS would tuck that rim pretty deep and close to the frame. Right?

got someone else wanting to get rid of some 15x8 Telstars with 4.5" BS and 5x5 botl pattern. will these work?

I am guessing that if I get this thing on track then I will eventually want the 15x10s so I can get a tire back there for traction.

15x10 with 4.5 to a 5.5" of backspacing looks pretty good. i also believe a 7.5" would be to much for a 10" rim, but perfect for a 12" rim... the telestars will work..

It sounds like maybe you could run a 2" spacer/adapter and come out with the correct fit. But I'm not sure how safe that is. I know a guy on another forum that did that with some 4-3/4 wheels on his fullsize. He raced with them and everything(I believe it was an 11sec truck). He told me to just make sure I buy quality spacers/adapters and inspect them constantly. But I don't remember who makes the adapters he used.
