Air Guard Tire-Pressure-Monitoring Valve Stem Caps
These handy valve stem caps from Air Guard give drivers at-a-glance info on their tire pressure to ensure tires are never running with low pressure. The stainless steel caps automatically calibrate themselves when installed on a freshly inflated tire, and they feature bright red LEDs that illuminate whenever the pressure drops too far below the recommended level. This set includes eight caps—ideal for two-car or eight-unciycle families—that can be reused on different vehicles thanks to their easy-to-recalibrate sensors.
