Tire Pressure Monitoring System

The problem with a TPMS is usually faulty set-up bu the owner and not the TPMS itself. If the coach was weighed and the tire charts say that you should be using 95psi MINIMUM in the tire, as an example, then the TPMS should be set higher. From reading the various posts on this forum, that 95 psi is what most people set their TPMS for. This means that the tire has to lose 10% or so before the alarm is sent. Who knows what damage is done to that tire when driving for xx miles with the tire under-inflated until air is added to bring it up to the MINIMUM required air pressure of 95psi. The same goes for ONE dual going under-inflated and causing damage to both tires. Others have said that they do not add air when the TPMS sounds an alarm when the tire was cold in the morning because after they get on the road, the tire will warm up and the pressure will increase.
For the TPMS to have any use at all, it needs to sound an alarm when the tire gets to the 95psi MINIMUM, and NOT 10% below 95psi. This means that you have to inflate your tires for a certain amount over 95psi, when the tire is cold before you have driven on it, to properly monitor and protect your tires. Then, when the tire pressure drops to 95psi, you will be warned to add air BEFORE damage is done. Any warning after it has dropped below the MINIMUM of 95psi is too late.
