Tire Pressure Light - What Does It Mean?

Types of TPMS Service

If the vehicle you're driving starts to have low car tire pressure, you'll be warned, thanks to the tire pressure monitoring system (TPMS) in your vehicle. The TPMS is often referred to as your tire pressure light. It comes on to warn the driver when a tire is significantly underinflated and not close to the recommended tire pressure. The main purpose of these systems is to warn Crystal Lake drivers if their tires are losing tire pressure, leaving the tires underinflated and dangerous.

Direct Monitoring Systems

Direct tire pressure monitoring systems (TPMS) warn McHenry drivers when the air pressure in any of their tires drops at least 25% below the recommended cold tire inflation pressure. Direct systems have a TPMS sensor in each wheel, generate pretty accurate warnings and cause the tire pressure light in the dashboard to come on if any one tire falls below a predetermined level due to rapid air loss.


Indirect Monitoring Systems

Indirect tire pressure monitoring systems (TPMS) warns McHenry drivers when a single tire has lost at least 25% of its tire pressure compared to other tires on the vehicles. It's a little less accurate than the direct system for Illinois drivers, but its still useful. The reason its not as accurate is because it doesn't specify which car tire pressure is low, and doesn't warn the driver if all four tires are losing pressure at around the same rate (like during the fall and winter months when operating temperatures get colder). Additionally, indirect systems sometimes generate false warnings.


Why is Low Tire Pressure Bad?

Tire Pressure Light

Driving your vehicle on tires with low car tire pressure can create unsafe conditions in a hurry, particularly in Richmond/Spring Grove bad weather. If your automobile tire pressure is too low and you continue to drive around Illinois, you could severely damage your vehicles tires, and you may eventually blow a tire. Driving with low tire pressure also impacts your gas mileage, car handling, and will reduce the life of your car tires.


Driving with Low Tire Pressure

Studies have shown that people operating their cars without the recommended tire pressure is common. It's been estimated that about one out of every four vehicles driving around Algonquin is driving without the proper tire pressure. That means that roughly one out of every four drivers is negatively impacting their vehicle's fuel economy and handling, and costing themselves money by reducing their tires' durability and tread life.

If you are unsure of which TPMS service your vehicle has, stop by Gary Lang Auto Group in McHenry, Illinois to have your car tire pressure checked. Since McHenry tire pressure systems aren't always 100% accurate, make sure you check your tires to help ensure they have the proper tire pressure, or have Gary Lang Auto Group check it against your tire pressure chart, at regular intervals.
