The amount of work involved with a 295/65R20 (35.4" spec diameter) tire, or categorically a "36", would indeed take that much more effort. I tossed it around in my mind and took some measurements. Ultimately decided against it but it would not be impossible for the motivated. There's a certain awesomeness in stuffing this amount of tire without bracket lifts and such.
Beyond what I documented here for my 35x12.5s
They keys to a 36s would require
- Body lift - 1/2" body lift would be required to avoid significantly cutting of the wheel well liners, at front. But also rear which is metal. Stock body bolts should be reusable as they have about that much additional thread. So just some 1/2" shims of which could probably buy a kit meant for the 100-series. May need to play with the radiator hood positioning, steering rack universal, and shifter. Totally doable and would only be a weekend job.
- Optimal offset would be +25-30mm for scrub radius
