The tire pressure monitoring system (TPMS) was introduced to increase road safety. According to recent studies of the Sécurité Routière, a French organization for road safety, it is estimated that 9% of all fatal road accidents are caused by tires with a wrong pressure and in Germany, DEKRA, states that about 41% of road accidents with physical injuries are related to tire's issues.
For non-professionals, a tire that has lost up to half of its pressure may appear normal, as stated by the National Highway Traffic Safety Administration (NHTSA).
Insufficient tire pressure affects driving safety under two basic aspects:
- Influences the traction, the maneuverability, the steering, the stability and the braking.
- Wrongly worn the tire tread and in addition to influencing the vehicle handling, put the tire at risk of bursting, a very dangerous event while driving.
75% of the punctures are preceded by a slow loss of pressure or incorrect tire inflation (www.safecar.gov), so to keep the tires in perfect condition it is necessary to check their pressure regularly.
The tire pressure monitoring system (TPMS) intervenes precisely in this area, automatically alerting the driver when a tire has a pressure of less than 20% or less than that indicated by the vehicle's pressure plate.
