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
