The #2 website is www.smartire.com (only one T in the name). I have used this system for several years. I had it on two plastic coaches and when I bought my Prevost it was not on it. I was never fully at ease driving, not knowing what my tires were doing even though I checked them on every trip, stop, etc.

The SmarTire systems monitors pressure and also temperature. So if a bearing or other wheel/drive component is failing the temp will be monitored and you will be alerted prior to a major failure.

The sensor is attached to the wheel by a large hose clamp, thus the tires have to be dismounted, and the signal is received by a dash mounted monitor. The problem alert is a sound and a red flashing light on the monitor.

I believe this system is more expensive than the valve stem mounted types but I feel it is worth the extra $$ for the value received. I have used it for the past 8 years and would not be without it.
