If you are running into an issue in which your TireMinder is reading a different pressure than your tire gauge, the first thing your are going to want to do is to get an accurate comparison. To get an accurate comparison, please use the steps below. Please note, you will need to be in Monitoring Mode in order to perform these steps.
- Remove the transmitter from the valve stem.
- Once remove, the monitor should read 0 PSI at the corresponding tire position.
- Use a trusted tire pressure gauge on the same tire and record the tire pressure.
- Screw the transmitter back onto the tire.
- Once back on the tire, the monitor should display the current tire pressure.
- Compare the two tire readings.
When comparing tire readings, please allow for a slight variation of pressure as each tire gauge will have various precisions. The most common precision is +/- 2 PSI with tire pressure gauges.
Why do you need to perform these steps in order to receive an accurate comparison?
There are many reasons ranging from heat, atmospheric pressure, altitude and weather that can cause pressure to change, even while standing still. For example, when we arrive at our offices in the morning our tire pressure would generally be around 32 to 33 PSI. Around noon, these pressures could reach as high as 36 to 37 PSI - while stationary! This is because the tire pressure is increased by the day's heat, which is also exacerbated by the parking lot, which slowly heats up your tires throughout the day. When you're driving, these factors will increase, increasing the likelihood that the pressure you registered with your tire gauge yesterday, will not be the same pressure you see on your TireMinder today.
