How often does everybody check their tire air pressure? I check mine about 3 times per year! I read where you should do it monthly. I know!! Laggert I am.
I set the TPMS alert threshold much higher than normal. The way it's set (in my generation, gen 3, anyway) is by pushing a button under the dash, and then it looks at whatever pressures the tires have now, and sets the alert threshold for a substantial percentage below that. Like, if I pushed the button when my tires at at their normal pressures, I would never get alerts unless they dropped into the mid-20s psi. So instead, I pumped my tires up just once to the max sidewall pressures, and I pushed the button then, and after that I let them back down to the pressures I normally run. That means I get the yellow TPMS light when they're just a few psi below my preferred pressures, and I air them up right then. It can be a bit of a nuisance in the spring and fall when temperatures change a lot, because every sharp temperature drop lowers the pressure enough to put the light on again. But then, I wanted to know about that, so I guess that's what I signed up for.
