That classic car you are riding in or towing behind your truck is quite the investment. It's not just about the money...it's about the blood, sweat, tears and long hours you put into her restoration. You blow a tire on the trailer you are hauling her on or blow a tire on her...you might not be able to get the chance to fix her back up. Performance Products has the answer with the Hopkins nVISION TPMS tire pressure monitoring system. Two stage PSI, high pressure and high temperature audible alerts allow you to pull over and see what is going on with your tires before it becomes a major problem. Monitor can sit on the dash, console, the seat next to you or hidden out of site due to the audible alerts. Driving to a car show? No problem! Sensors can be removed when you get there and replaced with conventional valve stem caps.
