You're not the only one with leaking tire valves. I have one tire with similar symptoms. Hey, by the way, does anyone happen to know if the TST507 pressure transmitter stops transmitting if it is removed from the tire? I usually take the transmitters off thinking I am saving my batteries.
I could verify on the monitor that it did stop transmitting.

How did you verify the cessation of transmission when the sensors were removed? I can understand that you may not have an indicated pressure on the receiver, but the receiver may have a low pressure threshold that won't display very low pressures. You're probably right, but I think I will call customer support on Monday and ask them to verify your experiment. I will let you guys know.
