i recently purchases the re6103 4.5'' superflex kit and i plan to put on 33x12.50tires on a 15x8 wheel.

my question is what backspacing would i need for this set up?...also i want to get american racing 767 wheel and i dont see a backspacing listed for this wheel, do i need spacers?or should i choose a different wheel with the recommended backspacing?

i dont think the ar-767 come with backspacing, so therefor do i need to think about a different wheel with the 4''bs or is there an alternative?

I've got 15x7 AR767s with 4" BS - they fit great with 32x11.50s as well as 33x10.50s

AR 767-5765 is a 15x7 with 0 offset, in a 5 on 4.5" bolt circle

In simplest terms, offset is the difference between the wheel-mounting surface and the centerline of the wheel, and is a function of the backspacing

Yup. My plan is to go to 33x10.50s in the future so I opted for the 7" rim to give it more sidewall coverage on the rim.

For a 33 x12.5 on 15x8 wheels you will want somewhere between a BS of 3.75 - 4.25.

Anything in there will fit and work well.

I run 4.5" of lift and 33x12.5 on 15x8 AR767 with 3.75 BS. Here is a pic. Don't mind the absence of a bumper. The paint is still drying on the new one.
