[Merlin76]

I know that there are a couple different options, just looking for the opinions of you all....

Thanks as usual....

ive got 15x10 with 5.5 backspaceing, and the new 36x13.50 iroks, 5.5 lift and hacked out fenders, dosent rub at all even at full flex. which tires are you looking at, these iroks are real nice, and arent wearing that fast, in relation to how soft they are

I'm running 3.5" backspacing with 37x12.50x17. I tryed 4", but the tires rubbed the coils and shocks during flex.

You must be talking about 5 X 5.5 being your bolt pattern. I dont see any way to run 5 1/2" for back spacing on our broncos.

I have 33 x 11.50 X 15" tires, running 3 5/8" Backspacing.

im running 36/12.50/15 tires on 15 x 8 wheels with 3.25 backspacing and they barely clear but then again a 76 has less room for backspacing than the previous years

5.5" BS might work with 17" rims, but definitely not with 15x10s. The wheels would'nt even bolt up due to the TREs.
