Hey guys, i'm currently running Goodyear Duratrac 33x12.5 on 20 inch rims. Bought the set of tires and wheels used on marketplace.
I think i'm running them at 40 pounds back and front, but i find the truck really twitchy when hitting bumps. Not sure if i am using the right term, but it's like if the rear of the truck wanted to come say hi to the front.

Needless to say, the truck handling is less than stellar, and i thought i would somehow give better hanling to the truck with harder sidewalls.

I have not tried to inflate the tires more ( kinda thinking the issue would be worse )
I did not try yet to deflate to 36 ( like it shows on my door jam for my 2022 )

Is it normal that the handling is so much worse? Last time the truck handled like this, i had a blown shock absorber on the rear left, but as far as i know, they are all ok on all 4 corners right now.
The truck does not have any kind of lift or anything. Beside the Wheels and tire, 100% stock on the non-air ride suspension.

I read online that rebels with the 18" have 55/45, but that seems a lot of psi, i don't want it to ride like a coffin.

You have less sidewall than the stock setup so the ride will absolutely be harder with similar psi. Harder/shorter sidewalls gives better handling in the sense that they deform less in cornering. On a track. If you want a smooth ride, you want the opposite. Let some air out and it will improve a bit. The bilstein shocks in the Rebel are also stiffer than other trims. They're not a TRX/Raptor type setup that are designed to absorb lots of high speed bumps, they're a traditional off road shock that is designed to reduce excess bouncing, which can contribute to that rear end skipping effect you're experiencing. You could get softer or adjustable shocks as well.
