A steady tire pressure warning light usually means one or more tires are underinflated, while a flashing light often indicates a system malfunction or a sensor issue.
When your tire pressure monitoring system (TPMS) light illuminates, it's important to assess the situation promptly. A steady light suggests you should immediately check your tire inflation levels and add air if necessary. If the light continues to stay on after inflating the tires to the recommended pressure, or if it flashes, it could signal a problem with the TPMS sensors themselves or another component of the system. Driving with underinflated tires can lead to poor handling, increased fuel consumption, and accelerated tire wear. A flashing light, in particular, warrants a closer inspection by a professional to diagnose the specific issue.
This information is for general guidance; always consult your vehicle's owner's manual and a qualified mechanic for specific diagnoses and repairs.
How often should I check my tire pressure?
It is recommended to check your tire pressure at least once a month and before any long road trips. Tire pressure can fluctuate due to ambient temperature changes; for every 10-degree Fahrenheit drop in temperature, tire pressure can decrease by about 1 PSI. Regular checks ensure your tires are properly inflated, which contributes to safer driving, better fuel economy, and extends the life of your tires by preventing uneven wear. A simple tire pressure gauge is an inexpensive tool that can help you maintain optimal inflation.
