There is no per-tire pressure display in the car, nor does this functionality exist in the MyMazda app. The car will inform you when tire pressure is low; however, you must check the pressure yourself manually.

No.

In the app: Vehicle Status shows Fuel, Odometer, Doors, Trunk, Hood, Hazard Lights.

Under Service, Health Check shows Lights, Tire Pressure, TPMS as simple check marks.

I have a 2023 3 and can confirm that I see actual tire pressures for all 4 tires, but I suspect the CX-5 still being on the previous-generstion infotainment system has something to do with the difference. Probably other subsystems are not the same generation as the 3/CX-30/CX-50/CX-90, etc.

For the CX-50, it does show tire pressure on the app. I can’t speak for other vehicles.
