What Does the Tire Pressure Warning Light Mean?

Tire Pressure Warning Light MeanHere at Dakota Ridge Auto in Littleton, we understand that vehicles these days come with all kinds of warning lights that can be confusing to decipher. However, if your tire pressure warning light comes on, it means just what you think – that one or more of your tires has low air pressure.

The dashboard warning light, which looks like a cross-section of a tire with lines through it, comes on when the tire pressure is 20% below what the manufacturer recommends. So, if your recommendation is for 35 psi (pounds per square inch), the light will come on when your pressure falls to 28 psi.

It’s important to note that 20% below recommended pressure is significantly under-inflated. This means that you will be experiencing degraded handling and that your tire will be running hotter than it should.

This can not only be a safety hazard, but your tires will wear prematurely and could even suffer a heat-related tire failure.

Don’t Rely on Your Tire Pressure Warning Light

Littleton drivers should NOT use their Tire Pressure Monitoring System (TPMS) warning light as their trigger for checking their tire pressure. They should still check their tire pressure at least once a month.

Some drivers mistake the tire pressure printed on the side of the tire as the recommended pressure for the vehicle. This is not the case. The information on the tire is the range the tire can handle.

The correct pressure for your vehicle is on a plate or sticker on the driver’s side door or door jamb.

This is the pressure your tires should have to match the engineered handling capacity of your vehicle. Please note that the pressure may be different for your front and rear tires.

What You Need to Know About Your TPMS

Your Tire Pressure Monitoring System does not have a regularly scheduled maintenance interval or typically require repair. However, the batteries in the sensors mounted in each wheel will eventually die, illuminating the warning light and necessitating replacing the sensor. Sensors can also be damaged by road salt and other contaminants.

Some TPMS systems monitor tire pressure for each individual wheel and will let you know that a specific tire is low – as long as the system has been reset after rotating the tires. Other systems will simply give a warning, and it is up to you to check all your tires (including the spare).
