New Truck Tire Pressure Question

[Razzman]

So yesterday I finally got around to doing the chalk test on the new LT285/65R20 Falken Wildpeaks. The test shows 60 front and 48 rear are perfect wear patterns. Of course I have TPMS error now on the rears but it does ride super soft for this truck. Might just bump to 50 rear to avoid changing the inflation parameters in Alfa. My door sticker states 65/65, never liked it that high in the rear.

2021 3500 SRW. Night Edition came with the 20" Firestone Transforce AT's. All tires inflated to 80 psi when picked up at dealer.
Door sticker states 65 psi front and 80 psi rear.
Wondering why fronts are at 80 psi, should I lower to 65?
Any thoughts or advice for me please?

2020 2500 Laramie, same tires. I'm impressed that yours were only at 80 lbs. My door sticker says 65 front and 70 rear. My truck showed up at about 85-87 lbs front and rear -- and that was in December in the northeast. Can't imagine what the pressure would have been if it was a summer delivery. So much for the "dealer prep".
