Correct PSI for my new tires?

Every Tesla I’ve ever seen delivered with 19s says 45.
The OP doesn't mention rim size so I always default to my cars settings, which is why I say to check the door jamb.

Thanks for the responds but I’m not sure you guys are answering my question. What I’m saying is that because the new 19” tires have a higher load capacity the tire store said I should use a 36 psi instead of the 45 psi written on the door jamb (they calculated it).

So do the new tires increased load capacity change the default psi?

According to this website they are correct. Tire Pressure Calculator

Regardless of the psi you set it to, I would check the tread depth every 3k-5k miles to see if it's wearing evenly. That will tell you if your tires are inflated properly.
