It looses air therefore, you have a flat tire so you should go to a mechanic! The tire pressure slowly drops causing the tire to wear unevenly and you to have less stability and control of your vehicle.
If air is leaking out, obviously the pressure will decrease to nothing. Find the leak and fix it.
a) the straight graph
needs a new heater core
the surface area decreases.
Low tire pressure or failed tire pressure sensor.Low tire pressure or failed tire pressure sensor.
The warming air would expand and the tyre pressure would go up.
From the Owner's manual :How to initialize the tire pressure warning systemPark the vehicle in safe place and turn the "POWER" switch OFF.While the vehicle is moving, initialization is not performed.Adjust the tire inflation pressure to the specified cold tire inflationpressure level. (→P. 565)Make sure to adjust the tire pressure to the specified cold tire inflation pressure level.The tire pressure warning system willoperate based on this pressure level.Turn the "POWER" switch to ON mode.Push and hold the tire pressure warning reset switch until the tirepressure warning light blinks slowly 3 times.Wait for a few minutes with the ON mode, and then turn"POWER" switch OFF
Tire pressure is related to what type of tire it is. the recommended pressure for the tire is on the side wall of the tire ========================================================== That is the MAXIMUM cold tire inflation pressure that is shown on the side of the tire
tire pressures will rise due to the tire heating up due to flexing and friction of it against the road surface. This is why the tire pressures are suppose to be set when they are cold.
Air leaves a tire when the tire valve is open due to the pressure. The pressure outside of the tire is lower than the pressure inside the tire.
It could, some vehicles do have a tire pressure sensor in the spare.
