Here’s a recent post I made of my first tow in a 2022 that includes a review at the bottom of the P.1

Increasing the Dueler tire psi to maximum (44 cold) I believe can make an improvement. Same with the Helwig bar that is an easy install low cost improvement.
I’ve used and like Michelin Defenders in load range E on 17” diameter in my 4th gen, but the new truck has 20”. Load range E for 20” is another size larger and a speedometer recalibration by the dealer would need to be done if choosing those.
When the time comes I’m replacing with Continental Terrain Contact H/T 275 /55 R20 117H XL. These are load range C (XL) 2833# and have a slightly stiffer sidewall with 51 psi max inflation. The Continentals rated #4 in Tire Racks comparison. The Michelin Defenders rated #3 out of 45.
Both would be an excellent choice, but when towing a slight stiffer sidewall could be an improvement. Be aware, that the stiffer sidewall will make the ride rougher.
