How To Differentiate TPMS Sensors From iTPMS Sensors

Tire pressure monitoring systems are supposed to become an investment in your safety and finances. They are also legally enforced in many countries in the attempt to reduce the number of accidents on public roads. Originally, the first sensors were invented in the ’80s, but they were not so popular back then. If you think about it, there are still a lot of cars that ride without these improvements too. A lot of people think they can care for themselves by checking the tire pressure before going on the highway anyway. Plus, when they drive around urban areas, they know that they cannot speed, so they can hear or feel any potential problems related to their tires. Therefore, they find the investment not worth.

But from a different point of view, the tire pressure monitoring system is a legal requirement. Besides, it can reduce the costs for your insurance too. The safer a car is, the less risks an insurance company takes, so it will offer better prices. Think about the mileage per gallon too. There is a reason wherefore car manufacturers provide a recommended tire pressure. Their cars are tested for the optimal performance and the lowest possible fuel consumption. As if all these were not enough, you clearly do not want to change tires once a year. A low pressure stimulates the tread wear. The braking distance is reduced too, while an overheated tire is very likely to blow, leading to severe accidents and even fatalities.

Unless you are the lucky owner of a car fitted with a tire pressure monitoring system, you should know that you need to implement this upgrade on your own. Reach to the nearest service and choose something that suits your car. There are normally two types of systems – TPMS and iTPMS.

Making the difference between TPMS and iTPMS

While the TPMS and iTPMS are the most popular types of products, you will find other different types as well, yet they are not so popular. All in all, the TPMS is the most common solution. These sensors are built into the valve stems. Every tire is supposed to have a sensor. The system also includes a battery run transmitter, as well as a receiver. The receiver is in the cabin, so the driver is aware of any potential warnings. All these parts are hidden inside the wheels. Therefore, they are not so easy to steal or see. In order to change them, the tire must be removed from the rim. Such situations arise when you need to change the transmitter battery. Almost every new car comes with this type of system, yet it also has a few side effects. It is quite fragile and costs a lot more than other alternatives.

On the other hand, iTPMS works differently. The respective sensors are not installed into the valve stems, but into the valve caps. Just like the other system, this one comes with a sensor for each wheel. Some products come with battery operated transmitters, while others do not. The best part about this system is that it can be installed or removed without having to take off the tires, balance them later and so on. Another great benefit is the cost, since these systems are clearly less expensive than the TPMS ones. But then, nothing is perfect, so it has some drawbacks as well. Most importantly, they are easy to spot if someone pays close attention to your wheels. Since they are identifiable, they are easy to steal. Feel free to check out these stunning TPMS sensors that are both easy to install and hard to steal.


Choosing the perfect system mostly depends on the type of car, as well as the available budget.
