Tire-pressure monitoring is commonplace on most new or relatively new vehicles, but the Cerebrum Smart Tire Sensors from Tire Stickers can do that plus a whole lot more. Mounted inside your current set of tires, each sensor is claimed to keep tabs on tire-rubber temperature, tread depth and alignment variation. And the best part is the sensors are reusable so they can be remounted inside new tires when the old ones are worn out (new base housings, available separately, are required). A downloadable app gives you up-to-date info on tire health at any time. Get full details and order a set of four Cerebrum Smart Tire Sensors for $340 at www.tirestickers.com.
