Been using a Bluetooth TPMS on my car which I got from Indiegogo crowd funding. Beats having to rely on a light on my dash when there is a problem. Cool thing is that I get to check my tire pressure even when I am not driving by just looking at my phone. I even ordered an extra set to put on my wife's car to monitor her tires after she had busted a couple of them by driving on low pressure. Anyone heard of them, it's called FOBO Tire. Will post some photos when I have the chance.
