Tire options limited------------

Marcohotrod said

the widest tire I would put on a 8" wheel is a 255=10" sidewall width. how much air pressure do U want to run? do U want the footprint to be full and flat? a 245 on a 6" wide wheel is too much, to get a full footprint U could only run around 18 psi. on the front I would go 205/65

Today I found a good tire size calculator. I put all my existing dimensions into my CAD program to scale and tried a bunch of combinations and offsets with 8" wide wheels. I landed on 255-60-15 as the ideal tire with either a 4" or 4 1/4" backspace wheel. I also found a custom wheel builder who can provide any backspace I need but I haven't verified them yet. So, I am getting there.
