Ever since the inflatable tire was invented, manufacturers have been advising us to maintain the recommended air pressure. Recently, tire-inflation monitoring devices have become mandatory in new vehicles, so where does that leave your used-but-not-abused family hauler? Now everyone can have the same piece-of-mind protection with a set of Air Alert valve caps from Aviation Upgrade Technology.
The firm's battery-powered, chrome-plated valve cap will set off a blinking red light on units designed for passenger cars and light-duty trucks whenever the air pressure in your tire falls to four psi (pounds per square inch) or more below the level your tires were at when the product was installed.
For Air Alert valves designed for heavy-duty trucks and buses, the activation point occurs whenever an eight psi loss is indicated. Prices start at $35 for the standard unit, or $39 for units that include an anti-theft sleeve. For details and ordering phone 760-208-1810, or go to ledpressurealarm.com.
