Picked up my car from SC for servicing and saw on invoice that my tires were checked and inflated to 50 PSI. Asked the service advisor and was told that Tesla now recommends 50 PSI instead of the original 42 PSI for my VIN (P85D w/245/35/21 Continental Sport Contact 5 tires). Not sure if it applies just to the D's or tires specifically. Can anyone else confirm this??
