F150 PSI On larger tires

So, I swapped out my factory 2014 f150 275/65/18 wheels with some newer 2019 275/55/20 take-offs. On the 18" wheels I would run around 35 psi and bump it up a little in the winter. I'm wondering what the psi is for the 20s on my 2014. The tires are goodyear wrangler all terrain adventure kevlar 275 55r20 113t if that matters and I'm currently running 36-37psi. Someone told me that the sweet spot is between 36 and 40 psi but that seems like a large gap. My door sticker says 35psi front and rear cold psi not exceeding 1402 lbs and I checked out a sticker on a 2019 and it reads 35 f&r cold not exceeding 1531lbs (same size tires mentioned for both..) 35psi just seems a little soft for a 55r tire. Anyway, for those who've done this swap, what's the ideal psi? Thanks
