There have been many discussions about tire pressure monitoring systems (TPMS). I am wondering if there are any new systems on the market that are easier to install or are more reliable? I had a system on my previous bus, and the biggest problem I had was the wheel monitors would start to leak and need replacing quite often. I occasionally got false readings, but I think that is fairly common. Has anyone found a system that is very reliable and easy to install? Has anyone been using a system that has just proven to be too much trouble or unreliable? I haven't yet made up my mind as to whether I want to install another system. Since I recently installed new tires, I don't want to remove them to install an internal system.
