Yup, here in SWFL the early morning temps dropped as low as 68F the last two days....Got a low tire pressure warning in the cool air, I guess the temps were in the high 80's to low 90's last time I checked our Model S tires; anyways, I measured 38psi all the way around and pumped our 21"s up to 42psi this afternoon.
Thanks for the reminder. Winter is almost here! I had to wear a long sleeve shirt when I went fishing last week. These colder temps are rough. I'm sure our friends in Canada feel sorry for us.
Afternoons we're still getting into the low 80's but that 20 degree swing is plenty enough to affect tire pressures.
