True 35s are a PITA. I'm guessing 315s are pretty easy since they are usually a bit smaller (typically 34.4 or so)
I'm running 305 MTRs 34.1"... They work incredibly well offroad and i have no rubbing in any conditions. The truck surprises me in what it can do. Part of the key to that is keeping the weight down and getting as much travel as possible. I have a sway bar disconnect also... No sway in the rear.... (lockers, gears, a belly tuck and a well balanced suspension don't hurt either)
The formula:
- body mount chop
- 17x8 -10 4.1 BS (315s will mount on these just fine)
- Fender liners trimmed and pushed way up front....
- washer bottle relocated
- uniball UCAS
- at least 4.0* of positive caster 5 better If my alignment drops below 4 it rubs a bit.
I have long travel in the rear so have 3" bump stop extensions back there. Not sure if that would be required with std travel shocks and springs.
I'm pretty sure I could get 315s to clear, but might need a bit more caster up front and possibly a slight spacer on the front bump stop.
Overall, the 34s let me do anything I want with the truck. This is nothing crazy but here is a vid from Saturday. My truck is the Mag gray one... My buddies truck (silver) is on the same tire MTR but a 33".

Although these 5th gens are never going to hang with solid axle rigs.. when built right they can do things that people never expect them to be able to do
