Keeping your tires properly inflated is an essential part of your auto maintenance routine. All tires come with a recommended PSI (pounds per square inch) level to ensure smooth handling and maximum fuel efficiency. When tires are underinflated, it can result in a blowout that causes you to lose control of your vehicle. As such, if you notice that your tires keep losing pressure, it’s important to determine what’s causing it so the issue can be addressed before your safety and car’s performance are affected.

What Causes Tire Pressure Loss?

1. Damaged Valve Stem

The valve stem is a small component that sticks out of the tire where you put air in. Over time, it can begin to weaken due to constant exposure to harsh road conditions. These valves are usually made from plastic, which is waterproof but still prone to damage.

As the valve stems become thin or brittle in areas, a slow air leak may develop. Valve stems can also incur damage if they’re over-tightened. When valves fail, it’s often necessary to replace all four tires.

2. Puncture

Tires are extremely durable, but driving over sharp objects can pierce through the surface, leaving a hole for air to escape through. Punctures can be caused by nails, sharp rocks, broken glass, and screws.

A punctured tire may gradually lose pressure over a few hours or even a couple of days. If it’s caught early enough, an auto maintenance professional may be able to patch the hole until you can buy a new tire.

3. Corroded Wheel

Your tires are attached to wheels, which have a tire bead seat to help increase brake clearance and prevent air loss. Unfortunately, wheels designed out of diecast metals can eventually rust and corrode, and as a result, the seal where the tire meets the bead seat will deteriorate and allow air to leak out.

Corrosion can also cause wheels to lose their shape from road vibrations, eventually leading to degradation of the tire’s sidewall and air loss. If your auto maintenance shop can’t remove the corrosion, the wheels will likely need to be replaced.
