Accuracy
of Pressure Gauges and TPMS
No reasonably priced tire pressure gauge is going to be 100% accurate. Likewise, NO TPMS is going to be 100%
accurate. What's important is that they are reasonably close and relatively consistent. You engineers and pilots
probably have
steam corning out of your ears after that last sentence!!
Maybe this
will help .....
The TireMinder transmitters are accurate to 1 psi.
Tire Minder brand pressure gauges
(mechanical
or digitaQ are among the most accurate on the market at
2 psi.
So, if you are running 100 psi
in your tires, you could have a 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. We have
had calls from customers doing
their initial installation saying all 8 or 10 TireMinder® transmitters are reading 9 to 11
pounds low!!! Can you guess what the problem is?? What is important to understand is that the TireMinder® ilO
(and any other brand for that matter) is designed to warn you of changes. For example, it really does not care
whether it starts at 97 psi or 108 psi. It is the changes and deviations from the baselines you need to know about.
