Valve Stem and Sensor
Whether you get your used tires from
Northwest Tires & Auto Care
or somewhere else, we want you to be aware of the valve stem and sensor
associated with your tire. Both of these items are very sensitive and
could be damaged if the tire technician is not qualified and/or
experienced. Here is a description of the valve stem and sensor:
VALVE STEM
A
valve stem is a self-contained
valve which opens to admit gas to a chamber (such as air to inflate a
tire), and is then automatically closed and kept sealed by the
pressure in the chamber, or a
spring, or both, to prevent the gas from escaping. They are most commonly used on
automobile and
bicycle wheels, but also for many other applications.
When damaged (see picture above), Valve Stems can leak air as if your
tire has a slow leak. Above is a picture of a damaged valve stem that
has dried out and leaks air from the cracks. You can check if your valve
stem has cracks by flexing the stem as shown in the picture to the
right. In addition, during the process of changing a tire, the tire
technician can damage the stem if he or she is not aware.
Sensor - A
tire pressure monitoring system (
TPMS) is an
electronic system designed to monitor the
air pressure inside the
pneumatic tires on various types of vehicles. TPMS report real-time tire-pressure information to the driver of the
vehicle, either via a gauge, a pictogram display, or a simple low-pressure warning light.
Sensors are very delicate and rest on the inside the tire. They are
easily damaged during a tire change. Make sure your tire technician is
aware of its placement when the tire is on the tire changing machine.
The sensors cost almost $100 to replace and are best replaced from the
dealer.
At Northwest Tires & Auto Care, we have your best interest at heart.
Valve stems and sensors are important for safety and comfort and all
drivers should be aware. Our tire technicians are highly experienced and
qualified when it comes to tires and will take good care of you.
