@dothatagain - I'm loving this setup! OEM 17" wheels with 37" tires has been working very well. Plenty of power when I need it. The AEV Pro Cal worked perfect for adjusting to the 37's.
A few things to report however:
1. The Maxxis Razr's did not wear as well as I had hoped . Even with tire rotations every 3K miles faithfully, they didn't not last more than 12k miles (although I could have gone longer if winter wasn't near). I ended up selling them with some tread left and putting a set of 37" Cooper Discoverer STT PRO's on.
2. Definitely get rubbing with mild off-roading (thankfully I do mostly light trail - unfortunately I don't get to do anything more). However, I have not done any trimming. Minor rubbing on the radius arms at full lock.
3. Airing down may be an issue with the OEM wheels, but I have not done that.
Overall, super happy with the setup. The OEM wheels keep the tires mostly under the truck so I don't get rocks flung up and paint chips. I am considering a 4" lift but have not yet convinced myself to pull the trigger.
Side note: I am running 48 psi - it's been 5 - 10 degrees in the morning so they have been as low as 41 psi.
Hope that helps.
Maxxis RAZR MT I assume?
Yikes only 12k and they were cooked? I typ only ROTATE every 10k
Have you had the alignment checked?
I have SLIGHT rub on the radius arm bolts with 315/70/17 (35”) Wildpeaks on the stock wheels. I never noticed it until I saw the bolt heads were a bit shiny and there was a small witness mark ring on the sidewall lugs
