I can atest for the TST system (Truck System Technologies) as being a great system....I installed a set this summer after have a tire shredding that I was alerted to by a passing motorist. After installed, I'm very pleased with it's performance. The readout screen has a rechargable internal battery that once charged...you can put the cord away for the summer! Readout shows pressure & temp. And sensor batteries are replaceable.
