backspacing on a 15x10 wheel

[barneybasher1010]

What backspacing will i need to fit 33-13.5-15 tires on a 15x10 wheel on a 79 blazer? THANKS Also i would like the tires to stick out of the fenders a bit. The truck does have a 4 inch lift

My steelie 15x10" rims came with 3.75" backspacing. I know you will be fine with that running those tires.
