What causes a leaky tire valve?

Wear and tear is the main cause of a leaking valve. It has a mechanism consisting of a spring-mounted valve that closes tightly with the air pressure inside the tire. Over time, the stem valve may become brittle and cracked, which may increase the risk of air leaking through it.

Can you drive with a leaky valve stem?

We have good news for you! You CAN continue driving! The purpose of the air valve cap is to keep dirt and debris out and to keep air inside in case the air valve ever does leak (you can find out if it is leaking by spraying some Windex on the valve and see if it bubbles).

It’s not uncommon for valve stem caps to fall off. While a missing valve stem cap may seem harmless, it can lead to loss of air pressure.
