Just mounted 37” Nitto Recon Grapplers (13.5” wide) and 20” Black Rhino Recon rims (I know a lot of recon going on here) and couldn’t be happier! Also installed the terraflex spare mount that relocates the 3rd brake light to the center (also great).

What tire pressure do you recommend for mainly street wear in the Miami Heat 95% of the year?! 🌴

I have the same set up, 37x13.5x20 on my 392…. I also have the Teraflex relocation bracket. My tailgate is sagging and scratching pain off the inner doorframe. I also have the Mopar tailgate reinforcement bracket, it does nothing for the hinges. I have the Teraflex BRACKET reinforcer sitting in my garage waiting on me to get it installed. Pics of my saggy ass follows.

Wider the tire, lower the required pressure (generally speaking). The chalk test that people talk about is probably the right way to do it. With my 12.5 in wide tires, I have tinkered with different pressures.

AEV recommends 28 psi and that is what I ran my JK at. Even at that pressure, I still had more wear in the center of the tire, but that was over a period of years. I never experimented with lower pressures, but at 28psi, ride was good, fuel economy did not seem to be impacted that much, but I'm not trying to maximize fuel economy.

So, my advice would be 28 psi. It rode better than 37 (factory) tire pressure and tire wear patterns were acceptable. I thought 28 sounded low, but it makes sense if you take into account how wide our contact patch is.

I am running 28 psi on my 2021 XR and it is fine. When towing trailers with heavier tongue weight, I do blow the backs up to 33 or 34 psi to compensate for trailer tongue weight.

I noticed on my rear tires that they would run warmer when towing and that psi would rise more if tires were at lower pressures. Higher pressure result in less flex and less heating up, thus psi rises less from the starting point if you start with a higher tire pressure. Everything is a balancing act.

Thank you for your service and your sacrifice!
 
I recently purchased 35 inch NIttos. How do you like the Tereflex bracket? Unfortunately it looks like I need it.

This is extremely helpful! Really appreciate you sharing. I’m thinking of going with the terraflex bracket also. What kind of roads are you on and what tire pressure you running?

Yes on initial read that sounds low! But I’ll give it a try and see how they feel/wear. Thank you for the detailed response!

Roads aren’t bad, a pretty good dip in the road near my house that hit daily. I’ve only been off road a couple of times. It took 4 years before I had to upgrade on my JK. I have no shaking or vibration while driving either. 32psi in front, 30 in rear

What lights do you have in your bumper? Do you have them wired to come on in R?
