What a difference 4-psi tire pressure makes. I have a 10-month old 70D 19" Cyclone and regular suspension. For about 2 months I've been driving at 41-42psi tire pressure instead of 45. (What can I say, I've been avoiding gas stations, so I waited long enough for my next appt with Tesla so they can repressurise my tires.)
The other day when I got my car back from the Tesla service center, my car drove so much smoother... like driving on air. So...smooth. I felt like I was driving a new car. Especially since I just got my regular dashboard replaced with the alcantra one. Tesla's initial mistake upon delivery. Anyway, my tires were back at 45 psi. (46 when the tires are warmed.)
I can only imagine what those 21" wheels would feel like... :-( especially without the Air Suspension upgrade. Must be less-smooth like when my tires were at 41.
Last week, it was so hot when I was in Pasadena, my tire pressure went up to 48psi all by itself parked under a tree.
