Tire Monitoring systems,

I have the Tire Minder System click on both truck and fiver tires, the ability to see the pressure and temperature at a glance and being warned if either are failing will save you thousands of dollars and inconvenience. Tire Minder is a real class act to deal with and they offer free replacement batteries annually which I think is pretty cool, they just re-designed the system to add some new functions that we on the road have suggested to them, mine is the original and aside adding the signal booster (which as a previous customer It was given to me at half off) it has served me very well, last trip home it went off indicating a loss of pressure on my fiver's tire, it turned out that the stem's nut was loose and it was bleeding air, a quick tighten and top off the pressure and I'm back on the road, not sitting on the side of the highway with a large hunk of my fender destroyed by a shredded tire waiting for good sam! Well worth the money.
