TPMS (Tire-Pressuring Monitoring System) is a standard technology present in all 2008 and newer car models. The function of TPMS is to monitor tire pressure and alerts the driver if it becomes dangerously low. The reason behind this development is the TREAD Act, enacted by Congress in 2000. The act was born as a response to the fatalities of Ford Explorers with Firestone tires, wherein it endangered the lives of many drivers and passengers.
Included on the TREAD Act is the implementation of TPMS in every vehicle. Using this technology, the car owner or driver will know if the tire pressure is too low or too high. With this, it reduces the risk of road accidents such as swerving, spinning, and crashing. Moreover, it lessens the chances of brake system failure that is often a result of incorrect tire pressure.
How Does it Work?
TPMS only alerts the driver when the tire pressure is below 25 percent. There are two types of TPMS; these are Direct TPMS and Indirect TPMS. The former uses a sensor mounted on the wheel. The sensors measure the air pressure on each tire. If the tire lacks pressure, the sensor transmits the data into the car’s computer system.
On the other hand, the indirect TPMS works with the vehicle’s Antilock Braking System wheel speed sensors. If one of the wheels hits below 25% air pressure, the wheel will roll at a different speed. The system will transmit the data to the car’s computer system. The information will flash on the dashboard.
Do You Need It?
TPMS notifies the driver when the car’s tire pressure is too low or if it is going flat. The system reduces the risk of accidents that are usually caused by low air pressure on tires.
While TPMS determine if tires have low air pressure, it is not much of a help in avoiding tire blowout. Why is it so? See this great post to read more on tire pressure.
Overinflated Tires and TPMS
Notice that TPMS only notifies if the tire has dangerously low air pressure. It does not alert the driver if the tire contains excessive pressure or is about to blowout.
Driving during the summer season – wherein the temperature is rising – increases the risk of a tire blowout. Remember that tires contain gasses. And gasses expand as the temperature rises. Consequently, the tire PSI rises by one point as the temperature increases one degree.
Moreover, as you drive, the tires are rubbing against the asphalt, which results in friction. The friction adds more heat to the tires. And since tires are made of rubber, it could blowout as it continuously expands.
How to Prevent Tire Blowout?
The best way to avoid tire blowout is to let the tires cool down. Also, make sure the tires are not overinflated. Always follow the manufacturer’s guidelines about the vehicle’s tire pressure.
Though TPMS can help you, it is wiser to bring a tire pressure gauge when traveling. A tire pressure gauge allows you to monitor if the tire requires pressure bleeding or needs more.
