15x10 Rally Wheel - Fitment?

I want to put 15x10s on the rear of a 75 C10, no suspension mods.

What backspace should I be looking for, for the best look and fitment?

(I'm planning to use a pair of NOS 15x8s in the front, 4.5 backspace).

Several sizes. You can bolt the stock 8" on the rear & measure how far inboard you can go, 2". Or go inboard 1" & outward 1 inch. Is 15x10 the only option? Going in 1.5 inch & out 1.5 for a 15x11.

I'm running 15x10 Rallys on the back of my 83 with a 5" BS and 295/50 TA's, no rubbing, also 15x8 on the front with 4" BS.

Re: 15x10 Rally Wheel - Fitment?

Thanks. I think all the OEM 15x8 truck rally wheels were 4.5 backspace if I'm not mistaken. I'm just going to use a pair of those for the front, probably with 245/60 tires.

The 15x10 is obviously custom. I've seen used pairs with 4.5 backspace but I know that Wheel Vintiques used to sell them with 5 backspace too. I'm looking at a pair of used 15x10s this weekend and will check the backspacing on them. I think if they are either 4.5 or 5 backspace they should work, especially since this truck isn't lowered. Probably with 295/50 tires. That should result in the same sidewall height and bulge front and rear.
