It all boils down to what the tire is rated for and how hard it is. A higher psi will help with gas mileage. But a lower psi will make a smoother ride.

56 psi?!? Damn that's a little high. And don't go off of what it says on the sidewall, that's usually max psi. If you can't find the tires specific recommendation go off of the door placard (VIN sticker)

I would run 32-34psi front and back. keep an eye on the wear in the middle, make sure its even if it wears on the sides then needs air vs middle that has to much air.

40% over max psi. On brand new tires, it works. Allegedly tires are capable of handling 2,3,400 times their max. I would never suggest that to anyone, please do not try it, but talking to people online about tires, new production tires are extremely strong.

I wouldn't go past 150% max, ESPECIALLY if they are not new.

Run 32-34 that will work great, and keep the car aligned good. Rotate regularly unless staggered then inflation and alignment is even more important lol

I would suggest what another person mentioned, going off of the sidewall. I know my stock v6 17s had a different max than the stock 18s. Your car sticker, I believe, is made for Yeh stock tires. Whatever you do, you are better off being safer than sorry. At the end of the day, cracks, dry rot, and damaged tires cannot take a higher psi or as much of a beating.
