It's nice to see people are checking tire pressure with more than one gauge.
I imagine I am into cars, understand the physics, so check my tires weekly.
It's really the most important safety / performance part of owning a performance car = the tires.
I run my winter tires (factory 19" Pirellis) at the recommended pressure: 49 psi
but the summer 21" factory tires I use 45 psi ... such a low profile tire needs a little help with PA potholes.
"Why do I need to know this? Will I ever need to know this?" In HS chemistry we learned: PV=nRT
.... when the temperature drops, check your tire pressure:
look at the sticker on the driver's door pillar. 21" 35 series sidewall factory recommended is 42 psi
but that's too low to prevent pothole bubbles. Lot's of posts here about sidewall bubbles ( I blame the owners ).
I've been pumping them to 45 psi / 310 kPa. So far so good. Ride is fine. The suspension on this car is simply amazing.
Winter tires 19" are fine with the recommended 49 psi / 338 kPa If you wait for the TPMS light to come on ... you are a child.
Not cool to rely solely on TPMS. Tires are too important, and the TPMS, like the Czech engine light, need a bit of this:
because Lucid doesn't want the owner to be able to reset the TPMS when they swap to seasonal tires themselves? I guess the folk who can afford this car don't wipe their own asses either.
Yes the pencil tire pressure gauges are notoriously inaccurate, but having one or two in your door pocket makes you a real pilot...
you do a walk-around before you take the right seat...
... you have the micro fiber towel for polishing the windshield.

Be cool. Go out an check your tires. It's worth 10 min. of your life.
