Why Is My TireMinder System Reading a Different Pressure Than My Tire Pressure Gauge?

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. You will need to be in Monitoring Mode in order to perform these steps.

Remove the transmitter from the valve stem.
Once removed, 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.

WHY DO YOU NEED TO PERFORM THESE STEPS IN ORDER TO RECEIVE AN ACCURATE COMPARISON?

To receive an accurate comparison between a tire pressure gauge and a TPMS, or even one gauge to another, the pressure must be retrieved at the same time. If the readings are not taken within the same timeframe, you will not receive an true or accurate comparison.

PRESSURE CHANGES OVER TIME

There are many reasons ranging from heat, atmospheric pressure, altitude, and weather that can cause pressure to change, even while stationary. When driving, these factors increase the likelihood that the pressure you registered with your tire gauge yesterday will not be the same pressure you see on your TireMinder today.

PRESSURE VARIANCE BETWEEN GAUGES

Each and every tire gauge or TPMS will have a varying level of accuracy. For instance

TireMinder brand tire pressure gauges are among the most accurate on the market at ± 1 to 2 PSI.
The TireMinder transmitter is accurate to ± 3%.

If you are running 100 PSI in your tires, you could have a tire gauge reading 2 PSI high and a TPMS transmitter reading 3 PSI low, leaving a difference of 5 PSI. This is not uncommon and is considered totally acceptable. What is important to understand is that the TireMinder TPMS, and any other aftermarket TPMS for that matter, is designed to warn you of changes. For example, whether it starts at 97 PSI or 108 PSI, it is the changes and deviations from the baselines that are the primary concern.
