Alright so I've done a ton a research and still can't find a solid answer. I have an 08 sierra z71 NNBS on the 4.75 RC lift. Currently I'm running nitto terra grapplers 285/70r17 with 2 inch spacers, slightest squeak at full lock in reverse. I'm wanting to switch to 285/75 r17 (33.9x11.3) Toyo open country AT'S. Can this be done/how much trimming would be required?? Also just ordered a set of procomp 17x8 rims with 0mm offset/4.5 backspacing. Any input would be great or if anyone on here is running a similar/same set up

No, you double posted the same question. And the answer is available if you're willing to do some math and learn, that way you don't have keep asking if you want a change going forward. It's better to know how and why, than just if.
