Tire pressure on 18" and vibration at 60-70mph

I've recently upgrade to 18" and had bad vibration at high speed 60-70. 80 is fine. End up playing with tire pressure and the people install the tires use 36PSI. Looks like the vibration is minimized by increase this to 42PSI/40PSI, also I can't believe that the ride is so much better and smooth. I think larger wheels need higher pressure.

What is the correct pressure on 18" tires?

perhaps your tires are out of round?

If you get a new vibration with new tires, you need to go to the shop and get them adjusted. Don't vibrate your car to death because of some new tires.
