Tire Pressure Warning Light On – Blame The Cold Weather
It’s the first cold fall morning, and suddenly you’re faced with that annoying tire pressure light coming on; why? The weather plays a big part on the pressure in your tires. Tire pressure drops about 1 psi for every 10 degrees F drop in ambient temperature. Additionally, tires lose as much as 1.5 psi per month as air escapes the tire and rim naturally.

You don’t need to read any further, unless you’d really like to know the nitty gritty of how your car’s tire pressure monitoring system works. Just call or stop in, we’ll test your TPMS, correct any problems, and reset the light for you.

How does the new Tire Pressure Monitoring System (TPMS) work?
Tire pressure monitoring systems continuously monitor the pressure in the tires through sensors located in the tires (direct system) or the use of wheel speed and other vehicle sensors (indirect system). The information collected by the sensors is transmitted to an on-board processor that interprets the sensor signals and warns the driver when tire pressure is below the minimum acceptable level by illuminating a warning lamp.

What does it mean if the TPMS warning lamp illuminates?
When the TPMS warning lamp on the instrument panel illuminates while driving, it means that the system has detected at least one tire with a pressure below the accepted minimum psi for the vehicle. The tires should be inspected and the tire pressure checked as soon as possible. The lamp will extinguish after the tires are properly inflated.

What does it mean if the warning lamp goes on and off?
On cold mornings, the warning lamp may illuminate for a short period of time and then extinguish. This type of warning lamp response is likely caused by marginally low tire pressure that dips below the warning threshold over night but rises to an acceptable level as the tires heat up through vehicle operation or an increase in ambient temperature. The tires should be inspected and the tire pressure should be checked. The lamp should not illuminate when the tires are properly inflated.

Why is proper tire inflation important?
Proper tire inflation is essential for safe and efficient vehicle operation. Safety experts estimate that 25 percent of passenger vehicles are operated with tires that are under inflated. Vehicles with properly inflated tires experience optimum ride and handling characteristics, shorter braking distances, longer tire life, and improved fuel economy.

Is low tire pressure easily detected by eye?
Under inflated tires are visually difficult to detect. It is recommended that tires are inspected and checked monthly with an accurate gauge. The TPMS is not intended to be a substitute for regular tire maintenance. Drivers should consult the owner’s manual for information on replacement tires and use of the spare tire.

What are the safety benefits of TPMS?
It is estimated that TPMS will reduce the number of annual motor vehicle crash fatalities by about 120 and the annual number of injuries due to motor vehicle crashes by about 8,500, when all passenger vehicles are equipped with TPMS.
