A car knows it has low tire pressure with the Tire Pressure Monitoring System (TPMS). It uses direct sensors to measure real tire pressure and send alerts to the dashboard. Alternatively, indirect sensors estimate pressure by measuring wheel spin. Both systems notify the driver when pressure is low.
The TPMS consists of sensors located inside each tire. These sensors detect the air pressure within the tire and send this information to the car’s onboard computer. If the pressure drops significantly, the TPMS activates a warning light on the dashboard. This alert helps ensure that drivers address potential tire issues promptly.
There are two types of TPMS: direct and indirect. Direct TPMS uses individual sensors in each tire to measure pressure directly. Indirect TPMS estimates tire pressure based on wheel rotation and speed, comparing it with optimal values.
Understanding how these systems operate can prevent hazards, enhance fuel efficiency, and prolong tire life.
In the next section, we will explore the benefits of maintaining proper tire pressure and how it impacts vehicle performance and safety. This knowledge will help drivers make informed decisions for their car’s maintenance.
