BullDog Winch's automatic tire deflators make it easy to air your tires down for your next off-road expedition. Just thread the deflators onto your tire's valve stem and use the locking nut to adjust its PSI threshold. Later when it's time to air your tire down, simply thread the deflator back on to automatically drop your tire's PSI by the pre-determined amount. A set of four deflators are included to cover all of your truck's tires.

Deflate your tires with speed and precision with a set of Bulldog automatic tire deflators.
