Suggested tire pressure
My tire pressure has ranged from 39 to 41 PSI on all 4 tires since the RX 350h was new on Jan 25th. I know it has a negative affect on comfort of ride and noise. Are any of you experiencing the same, and have you lowered the PSI to the suggested 33 PSI?

Is that 39-41 psi with tires hot or cold. If cold, that a bit on the high side. I usually run 1 psi over the recommended.

It will also negatively effect tire life.

You’ll get uneven wear with the center wearing out before the outside portions. https://www.firestonecompleteautocar...ate-car-tires/

Almost all new cars that I have purchased have had their tires overinflated when I picked up the car. Our 2023 RX350's tires (21") were inflated to 41 psi. all the way around. I bled them off the next day to the recommended 33 psi.
