jimkate Report post Posted January 1, 2015 I empathize with all the thoughts about the inaccuracies of tire pressure monitoring systems. I have used a TST system for several years, and have not felt that I was totally happy most of the time. Finally I sent the system back for examination, repair or replacement. I received the system back from TST the morning we were hitting the road. I'm an old diesel mechanic, driven truck for years, so I thought 'I'll set this up tonight.' I walked around, checked all the tire pressures and we hit the road. We stopped twice that day. Each time I checked the tires and the bearings with my hand. All was good. All was cool. Late in the day we decided to pull into a truck stop for the night. As we stepped down from the coach, the front tire was flat! Not only flat, the bead was broken from the rim, and the rim had been running on the tire sidewalls! You could have knocked me out with a feather! I had not felt any change in the handling of the coach. The last half hour on the highway, we were floating along at 65 MPH. Oh boy! Fortunately the truck stop also sold and serviced truck tires. With my wallet a bit lighter, the next morning we drove away from the truck stop with new steer tires installed and balanced. The friendly tire man helped me to install the tire pressure monitoring sensors. He thought that it would be a good idea to keep the sensors on the wheels. I agree.

jimkate Report post Posted January 1, 2015 The false positive readings have driven me nuts with the TST systems, especially on the toad. When the sensor stops reading from one position and then starts again in 5 -20 minutes and alternates on all four wheels is unnerving to say the least and when I say "stops working", its like the wheel fell off. They may work fine one day and then not the next. I understand the difference in pressure reading from an accurate gauge but when the sensor indicates 40# when the actual gauge pressure on a rear tire is 85# is not acceptable to me. Once the pressure increases after driving a few miles the sensor pressure may or may not jump to 90-95#. Like you, Bizsmith, I'm more concerned with the toad having a tire issue. I wouldn't put up with this. I would package everything up and send it back to TST for examination, repair, replacement or refund. I have never believed that my TST system was perfect, but I have been impressed with the folks at TST to try to support their product. I do believe it is wise to have a tire pressure monitoring system, irregardless of brand. Jim Share this post Link to post Share on other sites
