How To Monitor Tire Pressure To Gauge Effects of Cold

1. Look either on your tires or in the vehicle manual for the required tire pressure for your tires. You need to know this before attempting to monitor the pressure of your car.
2. Remove the small caps from the tire valve. Make sure to put them in your pocket or in a safe place because you need these to close off the valve after you are done checking the tire pressure.
3. Press a tire pressure monitor up against the valve of the tire. In a few moments you are going to be given a pressure readout on the monitor of the device. Test the pressure for all of the tires.
4. Check the tire pressure every few days to see whether there is any loss of air. If the tire pressure falls below the recommended unit, you need to add air to the tires. It is possible to use a bicycle pump, however, it can be hard work to pump up the tires, especially if the air pressure is far below what is needed. Local gas stations should have air pumps, many of which are free. If the air pump does not have a pressure monitor, fill the tires with air and periodically read the pressure with your pressure monitor. Once you have achieved the recommended level, move onto the next tire.
