What are your Tire Pressure Monitoring/Adjustment Habits?

[Lazy2.5]

I own a 2015 Mazda 6 that does not tell me my tire pressures. It has an older style of TPMS that simply alerts you if one of your wheels are spinning faster than the others.

I bought one of these: Fanttik X8 Apex Portable Air Pump & Tire Inflator

Here in Canada, temperatures fluctuate dramatically from day to day, between days and nights, etc.

I read online that tire PSI changes by about 1psi with every 5-6C change in ambient temperatures, so that is usually when I check my tire pressures and adjust as needed.

If the suns rays are coming into contact with the tires on one side of the car, I will have to drop their pressure by 1-2PSI to match the other side.

I typically inflate to a target of 1PSI less than what is specified in my door, because I often drive in the mornings while ambient temperatures are still increasing, and I find that the slightly lower pressure helps with bad roads.

On my CX-5, when I'm ready to readjust the tire pressures, here's basically what I do:

• Late in the day, inflate at my local gas station. 40psi, usually. Then drive home and park.
• First thing next morning, adjust pressures and verify using an Accu-Gage pressure gauge.
• Reset the system.
• Every other time I adjust the pressures, I check the spare tire.
• As my driving is almost all pavement, and almost all "regular/sedate" driving, I don't concern myself over side-to-side performance differences, changes based on surface differences (ie, gravel/dirt versus pavement, track vs street). The same essential pressures I use vary slightly front to rear, but otherwise I just ensure the adjustment keeps them seasonally where they need to be.

If I've had dramatic temp changes in the area, I'll often re-do the pressures to accomodate that current temp range. My area tends to not get huge temp swings from one day to the next, aside from the seasonal changes.
