not really sure that's possible. I believe the LMM wheel wells are smaller than the older trucks. I have an o6 so Havent had any personal experience with the new ones.
Big fender mod, cognito uca's.
I fit 35x12.50x20 on 20x10 rims w/ 0" offset on mine w/ torsions cranked all the way. Its doable, rides like crap and rubbed on the rear of the fender
