Re: Cars collect some interesting data...
I manually checked the air in my tires (0), and often discover a tire is low despite looking fine. It's not a reliable method. Running 5 psi low increases wear on the outsides of the tire, leading to more frequent replacement.
(0) The batteries in the tire pressure sensors are dead, and I'm not paying $500 to replace them. I'll use my $3 pressure gauge, thank you.
