Salutations and salutations, persons who possess CX30s. Inane inquiry. The tire management system is installed on my 2025 CX30. Pump up the pressure to 36 bar. When the air temperature rises, the tire pressure also rises, and the warning light turns on. Contrarily, it is also acceptable. Pressure drops when the fluid cools and fills up to 36. The lights turn on to alert you. Can I just set it and then forget about it? I am grateful.

That seems like a picky management sensor, without knowing the details. 😫 My sensor goes off every once in a while, usually when a wave of cold weather hits for several weeks. Once I fill up all of my tires, I'll be back on the road.

During the winter, I make one adjustment, and during the summer, I make another, and then I watch.

Indeed, that does sound somewhat delicate. The first really chilly day of winter is when I usually hear the warning, and that's about it.

No, the system will set it to reflect the current temperature. Tread may not touch the road if it is too low, and a smaller contact patch if it is too high.

Looks like it's overly delicate. While changes in temperature will cause pressure to rise and fall, the alert shouldn't be triggered unless the shift is quite drastic. Just from the heat that is generated when driving, the pressure goes up significantly. It is recommended to fill and check the pressure of the tires when they are cold. If significant weather changes are anticipated, I may occasionally add a bit more or a bit less.

In no world are they ever precise. After a while, it's still smart to use a reliable tire gauge to check the old-fashioned approach.
