I just received my V10 upgrade on my Aug 2019 build LR AWD Model 3 and today I noticed that all of my tires are set to 42 psi. Prior to my upgrade my tires were set to 45 psi since delivery at the end of August even though my driver door panel says it should be 42 psi.. So, is it possible that there is some coding in the V10 release that automatically sets the Model 3's to 42 psi? Anyone else notice that with their car after the upgrade?
