6. Reduced tire wear
The connection between reduced tire wear and what TPMS means within a vehicle is one of cause and effect, directly linked to proper tire inflation. TPMS, the Tire Pressure Monitoring System, actively monitors the air pressure inside the tires. Underinflation or overinflation leads to uneven weight distribution and contact with the road surface. When a tire is not inflated to the vehicle manufacturer’s recommended pressure, the edges of the tire bear a disproportionate amount of load, resulting in accelerated wear on the tire’s shoulders. Conversely, overinflation causes the center of the tire to carry the majority of the weight, leading to premature wear in the middle of the tire. The system’s ability to alert the driver to these deviations enables timely corrective action, ensuring optimal tire pressure is maintained. This direct influence on pressure management reduces uneven wear patterns, extending the lifespan of the tires.
A practical example illustrates this relationship effectively. A delivery van consistently driven with underinflated tires may require tire replacement every six months due to excessive wear on the outer edges.
