The factory sticker states 45lbs of pressure for front and rear. Isn't this pretty high - worried about hydroplaning in the wet weather we are currently having.
On my car with 21" tires the sticker states 42 lbs on all tires when they are cold.
For the 19" all-weather (on production model) tires that is correct, 45' front and rear.
Mine was delivered badly over-inflated - 55# or more in each tire.
My experience indicates that at higher pressure, the tread is held open, allowing water to be pumped away from the tire, and you actually get better wet weather traction. I will follow the recommended pressures.
During transit, prevents damage from the restraining rails etc.
A great article on tire pressure and hydroplaining.
murraypetera: Excellent link - thanks for sharing!
Veeerrry interesting! And not stupid. But ... no info on overinflation and water. ???
N.B.: it's "hydroplaning".
Maybe he's referring to ordinary water.
I wonder if overinflation reduces "edge contact", and causes loss of control for that reason. Makes me go "Hmmmm...".

Elon has tweeted that this week's announcement will now be the loan repayment, so supercharger announcement pushed back. Again. Urgh.
