Sick of using that ball point pen to air down?
Our automatic tire pressure deflators are the most convenient way to air down your tire. Initial simple setup calibrates the deflators to your desired psi so each time you use them you just screw them onto your tire valve and walk away. Deflators release the air in your tire and stop automatically at the psi you set them; so you can be doing other things while they air down.
