What Does Tire Pressure Mean?

Understanding Tire PressureHow to Understand the Tire Pressure Monitoring System

The Tire Pressure Monitoring System, or TPMS, light was added to the dashboard to alert the driver about an issue with the tires. But what does that mean?

Low Pressure
The TPMS light does not illuminate until the tires are significantly underinflated, 25% below the tire pressure recommended by the vehicle manufacturer. You can find the optimum pressure on a notice on the driver’s door jam. Low pressure can cause hydroplaning, decreased grip on the road, and reduced control of steering. This can cause accidents which will lead to financial strain and a lack of transportation.

When The Light Illuminates
As soon as you can, stop and inflate your tires. If you see the light come on, and disappear after a few moments, it is most likely because your tires were under inflated to near the 25% below threshold. An increase in the external temperature can change the tire pressure by 1 – 2 psi (pounds per square inch).

Regardless of conditions, correctly inflated tires are an important safety precaution that should not be overlooked. Maintain your car in it’s best condition by fully insuring it. Talk to an agent at Miller Insurance Associates for the best auto insurance for you and your vehicle.
