The tire pressure monitoring system indicator illuminates when one or more tires on a vehicle exhibit significantly low pressure. This warning is designed to alert the driver to a potentially unsafe condition that could impact handling, braking, and fuel efficiency. For instance, if a vehicle’s recommended tire pressure is 35 PSI (pounds per square inch) and one tire drops below a threshold, typically around 25% lower, the system will activate the light.
The presence of this technology offers numerous advantages, including improved safety due to enhanced vehicle stability and reduced risk of tire failure. Furthermore, maintaining proper tire inflation contributes to optimal fuel economy and extends tire lifespan, resulting in cost savings for the vehicle owner. Originally emerging in luxury vehicles, this feature is now mandated in most new passenger vehicles, reflecting its recognized contribution to road safety.
