The act, later signed into law, required tracking of, and response to, any possible danger signs from vehicles that would require a recall or posed a safety risk. Like most quickly-introduced changes, there were problems with the systems. But as technology improves, and engineers refine how the systems function, they're becoming smoother and more reliable. Read on and find out how the systems actually see inside your tire, what they see, and how your car reacts to the information.
Direct tire pressure monitoring systems use individual sensors inside each tire, and sometimes a full-size spare , to transmit information to a central control module. The sensors read internal pressure, and sometimes temperature. The information received at the module is analyzed, and any issues with any of the tires are sent to the car's vehicle information system, or low-pressure light. Information is most often sent wirelessly as a radio signal.
While some aftermarket systems are mounted outside the tire, most manufacturers use a sensor mounted inside the tire. This is where the expense for the consumer comes in. Each sensor has a battery with a life of about a decade. On most, the battery is not serviceable, and the entire sensor must be changed. The sensor stem is also subject to damage, as is the sensor itself, when the tire hits a curb or the car gets into an accident. And each time a sensor is changed, it generally has to be reprogrammed into the control module so it can be recognized.
The wireless system is also prone to problems and challenges, as well as being integrated with other car systems that can fail or become corrupted over time. If your vehicle's TPMS triggers the warning light, located on your dashboard, fill the low tire with the proper air pressure and this should make the light turn off.
If you are experiencing any issues with your TPMS or are in need of new tires, Belle Tire has more than , brand name tires available and ready for installation.
Vehicles that have direct TPMS may cost more than tires that do not have the system because of the extra parts such as the o-ring, cap and valve core. In addition, the system has to reset when, for example, replacing a tire. All tire purchases at Belle Tire, come with a lifetime of free value stem replacements and more. The main difference between the direct and indirect tire pressure monitoring system types is the manner in which they measure whether the tires are correctly inflated or not.
But which TPMS type is the better one? For everyday vehicles' and customer needs, the direct TPMS system seems to work better. This is due to the nitpicky control of indirect TPMS systems, which need to be recalibrated each time the pressure in the tires is changed or when the tires are replaced.
As a result, such systems give too much control to the vehicle's owner, which is probably not a good idea with critical safety functions. Furthermore, the biggest issue with indirect TPMS systems is that it only turns on the low tire pressure light when one tire has different pressure levels from the rest. However, when all four tires are deflated to a certain degree and function in that manner, the indirect TPMS will not notify the driver. This is still classified as low inflation pressure and it will cause an issue in the long run, but the indirect TPMS system will not notice it.
Under-inflated tires result in a shortened service life, a longer braking distance, a ruined fuel economy, and weaker traction. Therefore, direct TMPS sensors are more reliable for the average driver and they will result in fewer headaches during the vehicle's performance. The benefits of a tire pressure monitoring system TPMS are the exact opposite of what under-inflated tires cause.
When the tire pressure is monitored in the tires, it gives the driver control over the vehicle and ensures that it can perform in the correct manner. A tire pressure monitoring system will allow the driver to notice incorrectly inflated tires, and to prevent any possible problems when the low pressure light comes on. Proper tire pressure inflations optimize the tire's surface contact throughout its performance.
In this manner, they optimize the tire's traction, ensure a shortened braking distance, improve the fuel economy and ensure a slower and even wear along the tread area. Therefore, when the TMPS system receives regular maintenance and performs in the proper manner, it will ensure the vehicle's optimal performance.
When the tire pressure monitoring system TPMS needs to be replaced depends on its type. The main reason for the TPMS' replacement is damage, corrosion, and run-down batteries. The location of the tire pressure sensors on the wheels makes them face a higher possibility of damage during the vehicle's everyday performance.
This damage can be caused by a flat tire, potholes, or accidents, which do not necessarily just harm the sensors but can create bigger issues as well. Corrosion is usually the result of the road salt used in winter weather conditions. If the tires do not use snap-in, rubber valve stem TPMS sensors, the system faces a higher chance of corrosion and excessive rusting. Road salt can easily harm the rest of the vehicle as well.

TMPS sensors, like most electronic devices, run on battery life. Over time, these go flat, and the whole sensor needs to be replaced. And, as with replacing sensors for adaptive cruise control or automatic emergency braking, this requires a system recalibration. Maintaining proper tire pressure may not seem as vital as, say, making sure your engine has enough oil.
However, it is still an important maintenance task. If a tire is under- or over-inflated, Car and Driver explains, it messes with the contact patch. Plus, a tire without enough pressure flexes more, AAA explains, which causes excessive heat and accelerated wear. Under-inflation also increases rolling resistance, which makes you burn more fuel.
