running wide tires

I've got a 8" lift on my truck, its currently on 37x12.5-17's, at full lock it rubs on the leaf spring, and almost touches the rear part of the front fender. I want to run a 38x15.5 tire. What backpacing an offset do you guys recommend running? I dont mind having to trim the bumper, I also plan to get a taller shackle to raise the front end up a little more

Re: running wide tires

I run a 20x12,-44 offset,4.75 backspacing and no rubbing. That's with 35x12.50 tires and just a leveling kit.

Re: running wide tires

I think your problem will be solved if you run 20x10's with -24 offset.
