Tire Check by Kleen Wheels is a valve cap that indicates if your tire is in need of air with a red flag. Tire Check replaces your old valve cap. Just screw it on. Normally you will see a green button under the clear protective dome. When the tire pressure drops 2-3 psi (pounds per square inch) or more, a red flag will pop out of the green button. Fill your tire at your earliest convenience. Tire Check will automatically reset itself to the new pressure.

Tire Check accurately measures drops in pressure of 2-3 psi or more, and is constantly monitoring your tire pressure so you don’t have to. Tire Check valve caps work with any pressure ranging between 20 and 42 psi.

Climate causes air to shrink and expand, which can cause your tires to be improperly inflated. Tires typically lose 1 pound of pressure for every 10 degrees the temperature drops during the winter. Likewise, they expand in the summer. With Tire Check, just glance at your tires to see if they are in need of air.
