Proper Tire Pressure on 2020 1500 Rebel w/ 35x12.5x20 Nitto Ridge Grapplers

[tbaker1032]

Looking for proper front/back tire pressure recommendations.

2020 1500 Rebel
35x12.5x20 Nitto Ridge Grapplers
ReadyLIFT 3.5 Lift Kit
Currently at 59 psi in front and 49 psi in back

Seems like the ride would be kinda stiff, I have 305/55/22 Nitto”s
Mine are at 45..

Yeah seems like 59 in the front might give you a little more bounce than wanted. I have 35X11.5 Grapplers and I run 45 front and back. I inflate my back to 65 when towing the boat or having a heavy payload.

I can’t speak to the rebel but I had a F250 (which is definitely heavier than the rebel) with 35’s and if I wasn’t towing I would run 40 in the front and 35 in the rear and it rode as smooth as you can with E rated 10 ply tires. At your pressures now I better you are rattling all the fillings out of your teeth

Running pressure below 46 psi will set off TPMS lite, Rebel comes with 10 ply from factory and can only have a 20% difference from the recommended pressure listed in the door jam. I run my Nitto’s at 48 psi frt and back.

20% different from the door jam on a Rebel would be 44 front and 36 rear. I'd run them either 55/45 like the OEM pressure or 50/40. Inflate rears to 50-60 when towing/carrying heavy stuff.

Just curious can’t you rescan to lower the TPMS settings so the sensor doesn’t come on? Again no experience with Ram so trying to educate myself on these trucks

I think that's true. This is my first Ram so I haven't gotten around to testing everything out yet.
