Having had the MY for over 2k miles, I feel the ride is quite harsh especially over broken pavement and not so smooth roads. Was wondering what tire pressure I should lower my Gemini 19s to for a more compliant ride. They’re currently set to 44 psi which is what it came from the factory with. Cheers.

Tesla recommends 42psi, not 44psi. I've tried everything from 38psi up to 45psi. I don't notice an appreciable difference in harshness with any of these pressures.

Last time my Y was in the service center they pumped them up to 45. I could tell as soon as I started driving home. I lowered them back to 42 and can definitely tell the difference. May be tire dependent - I'm running Vredestien Qatracs.
