got the ok for new wheels, will 325/50 fit?

am looking at the american racing hopster:

American Racing Hopster Wheels: ARE-5505173 - summitracing.com

does anyone know if i will be able to run a 325/50/15 on the rear with a 15x10 and 3.75" backspacing? that is the only backspacing offered for the 15x10.

summit recommended 4.5" backspacing. just want to make sure the 3.75 will work.

and i dont have the truck or i would measure it. i need to get the tires ordered asap if i can run them.

thanks

Eh, I am not sure...3.75" with 325's might be cutting it too close...I would go with what Summit recommends...

I think summit is right. I just read some posts over in another forum and they said atleast 4.5 with a 295/50 tire. Check this out, maybe it'll help:

85 Chevy

it is hard to find a wheel i like with 4.5 bs though. thats is the problem. the hopster is only offered in 3.75 in 15x10.:confused:
