Looking good! Digging those wheels too.

Topic derail: do you have issues with fumes getting sucked back into the cab?
My 8.1 swap is getting near the tune phase and I know it will run cleaner but I am getting significant fumes in cab. The reason I ask you is that your exhaust is similar to mine and you have the softtop.
And nice shoes

Thanks! Yes I do get exhaust fumes if I take the rear window off. Its great for clearance but bad for fumes. If I keep the rear window on, its not bad. May have to re-design the exhaust again.Topic derail: do you have issues with fumes getting sucked back into the cab?

Really appreciate it!
Also - you can run less pressure in those tires compared to the PJs. Even broken in they are a stiffer sidewall.
Did they balance well?

I'm running 35psi in the front and 30psi in the rear with my 40" Trail Grapplers in the crew cab. I think it rides nicer with them versus the 37" Terra Grapplers I had previously.
The first trail I did, I ran them down to 18 first and they seemed too full. So the next trail I aired them down to 15 and the sidewall was super bulged out. They broke in pretty quick for me. But I also have a 4 ton truck.

The PJ's were an E rated tire in the size I had. These Nittos are not but I believe the 20's are. I have them at 35psi right now and they ride better and handle nicer than the PJs. I need to chalk them and get the pressure where the chalk wears evenly. Just haven't had the time with the other projects going on.
Good info. I might try to start off at those pressure and see how they chalk.
I run 30/35 as well on the 40” nittos and I’m well north of 7500 lbs loaded for the trail.
On the trail I’m at 10 in the rear and 12 up front.

Thanks! So 30 up front, 35 in back?
Are you guys chalking to determine air pressure?

I'm going to love airing these down and not having to worry like I did with the 16.5's.
No, sorry I wasn't more clear. 35 front, 30 rear. No beadlocks btw
I haven't tried the chalk yet....
When I pull my truck into our shop I can see the tread contact. I guess our concrete floor must always have a fine layer of dust on it so whenever I drive it in the shop I can see the contact area across the tread. That's been my method for landing on a tire pressure for a while now. I started out with the Trail Grapplers at higher pressures and then been lowering it 2 pounds at a time as I see the contact patch getting closer to the edge of the lugs. I'm pretty happy with where it is now. They should have close to 1500 miles on them now.
Did you make the mounting tabs or was is a bolt in part?
IIRC I used the 3 tabs. Some had to be bent a little to fit. I used a piece insulation foam on the side towards the fender to prevent rattling. Another tab welded on the other side would do the trick too. New holes have to be drilled with new bolts.
Awesome, thanks!
