I changed my mind on the 20x12 wheel and went for a less aggressive 20x10 with -12 offset to help bring the tires in and reduce rubbing. Still gonna go with the 37x13.50R20 and see how it goes. In the fabtech instructions it says you can fit a 37x12.50R20 tire without modding with a +20 off set so an extra inch wider tire should be able to clear with some trimming. I'll post results when done
Hey, I know it's been a while, but did you ever happen to get this thing done? I have a very similar situation. i have almost the identical truck as you. 2015 Platinum on 34" Trail Grapplers. I have 20x9 wheels with -12 offset right now and I hope to fit 37x13.5 tires under a 7" lift. What kind of modifications am I looking at doing regarding cutting and trimming?
(ReadyLift says 7" lift will fit 37x12.5 on +0 wheels for no trimming or rubbing)...
Offset will play a large role regardless of lift height. His offset is likely +20 keeping the scrub radius as low as needed to run 37s. +0 and deeper into the negative offsets is where you'll have to start cutting and trimming.

Yeah, you're right about that. I know the website says +0 will have no rub for 37x12.5 but I do have -12 and want 13.5 wide. I guess I'll just find out the results!
Seeing if you put the lift on already. Interested in the Ready Lift and wanted to see some pic.

I have not gotten the lift yet. The whole thing has to go together at once and that's $$$$. HAHA
I can't get the lift with the tires I have now and I can't get the tires with the lift I have now. So, I'm waiting on that mula.
For you guys that are running 35 and 37'' tires - has your low end performance suffered considerably?
One the tiresize.com calc.....moving from my stock 275/55/20 to 295/60/20 is the same equivalent of dropping the gear from 3.73 to 3.55....pretty significant....and that's not a 35''
