This stems from safety issues in the past that caused a great deal of damage and even death. The light comes on to let you know that one or more tires are below/above a safe pressure level; this allows you to make adjustments as needed to keep you and your car in safe working order. In addition to safety, the TPMS also has another benefit: it saves on fuel and helps tires last longer. How Does it Work? Well there are 2 systems that monitor tire pressure. Indirect TPMS and Direct TPMS. Both do a remarkable job, but work completely different ways. Indirect systems rely on the ABS wheel speed sensors to monitor tire rotation. A low tire or an over-inflated tire will have a different circumference than the properly inflated tires. This causes a slight difference in tire RPM and turns on ... read more
