Tire Pressure

Don't be surprised this week if your tire light comes on on the dashboard.
As temperatures drop in the mornings... tires with marginal inflation may drop below criteria and trigger the light

I check my tires a bit more than the recommended once a month at this time of year, and try to do it on the chilliest morning of the season so far. This way, I don't get caught off guard.

Mind that tpms system problems are secundary problems. Main concern is to have save pressures for your tires.
If cold outside, lower pressure , so more deflection of tire, so more heatproduction a cycle or at same speed. BUT also better cooling down of tire. So then tire-material still wont overheat , driving the speed constantly, for wich presdure is determined. Then you are allowed to highen up to determined pressure, for roadhandling and fuelsaving, and to prevent the light going on, but not needed for savety.
When hot outside, certainly dont lower pressure to determined needed, then yust overheated tire-material. This is only allowed "ZERO " times in tires use, gives beginning internal cracks, that tear further in time, whatever you do afterward. Then mayby only after 2 years that far , that tire blows, or treath separates, and then other factors are blamed.

And then it goes off when the tires warm up after driving.
