A Complete Guide On How Many TPMS Sensors You Need.

Tyre Pressure Monitoring System, or TPMS, has become more relevant in modern cars. Even more, people are also placing TPMS sensors in their RVs and on their trucks. 

Monitoring the pressure of your tires has various benefits, especially if you have multiple vehicles or enjoy driving off road with your camper.

However, the main question is the number of sensors you need for your vehicle. Is there a general sensor? Do you need multiple? How can you be sure about it?

This guide will go through all these details and more.

Benefits of TPMS

TPMS benefits

A TPMS is built to prevent your tires from deflating. This means that the main benefit is that you are aware of the pressure in every wheel of your vehicle. Yet, there are more benefits which we will list now.


A TPMS sensor will give the driver complete control of the car. Ensuring the vehicle performs efficiently and providing safety and awareness. In other words, it will notify the driver if there is an underinflated tire. As a result, it will prevent any possible problems when the alarm light turns on.

Optimal air pressure at all time

This device will ensure that all of your tires have optimal pressure at all times. As a result, you will have a better performance in fuel consumption. Additionally, it will prolong your tire's lifespan.

If you have a truck, constantly having the correct air pressure will ensure that other parts of it are not worn out faster. You can also get the same benefits in your personal car.

Optimal fuel consumption

If your tires are underinflated, it has a significant impact on the fuel consumption of your vehicle. It is estimated that from 10% of underinflated tires, there is a 1% increase in fuel consumption. Plus, more fuel consumption is connected to C02 emissions.

With a TPMS monitor, you will avoid these circumstances since you have direct control over your entire vehicle tires.

How Do TPMS Sensors Work?

TPMS how they work

Take out real time monitoring

The way your TPMS will work depends on the system you have installed in your vehicle. Modern cars generally have the Indirect TPMS system, but you also have a second one, the Direct TPMS. The latter is the type od TPMS that GUTA offers.


As previously mentioned, it comes installed in your car as it has become mandatory in many states in the US to have TPMS.

The way the Indirect system works is with your wheel's speed. If one of your tires is underinflated, your wheel will friction more with the road. As a result, a yellow light will flash on your dashboard. 

All indirect systems work together with your car's ABS.

These types of TPMS will not advise which wheel is underinflated. You will have to check each one making sure which one is leaking.


With this system, it is mounted on each wheel of your car. Each monitor monitors the air pressure of the wheel. Giving the driver a more accurate reading on each tire.

It notifies when a wheel has less than 25% air pressure, plus notifying which tire it is. As it is a system you must install, you can place it in every vehicle you own.

GUTA TPMS are all direct ones and will notify you of low pressure, fast leakage, high or low temperature, etc. As a result, you have a precise system that can make your journey safer.

Are TPMS Sensor Vehicle Specific?

TPMS type

Unfortunately yes. As we stated previously, some cars already come with TPMS sensors installed, which are vehicle specific.

Something similar occurs if you purchase your own TPMS sensors. They are vehicle-specific, so reading the specs before purchasing is wise.

The type of TPMS depends on the vehicle; if you own a truck, we recommend getting Solar Charging Tire Pressure Monitoring System | M20

type TPMS

The M20 is specifically equipped with high external sensors, making them ideal for eight and up to 10-wheel trucks.

As the name states, the Trailer Tire Pressure Monitoring System | GT107-2 is ideal for trailers. However, it can also be placed in your motorhome. Similar to M20, the main difference is that M20 can be charged with solar power.

type TPMS

The RV Tire Pressure Monitoring System | GT107-1 is the RV specialist. Even though it can monitor up to 10 wheels, it is more suitable for smaller vehicles.


Spare Tire and TPMS Sensors 


When purchasing a TPMS, you need to make sure to also install one in your spare tire. If you already have an indirect system, you do not need to add it.

Direct systems have an automated adjusting system. This allows the system to reset after the tires are changed automatically. The driver must make a few miles for the system to obtain all the necessary information and display it on the monitor.

Replacing TPMS Sensors

As with any device within your vehicle, TPMS sensors need regular checkups for proper maintenance. We recommend it since external factors may affect its performance. These factors could be corrosion damage and run-down battery life.

The biggest issue affecting your sensor is salt used on roads during winter. This can accelerate the rusting not only of the TPMS sensors but also of your vehicle.

The positive part is that these sensors are designed to last 5-10 years.

If you need to replace your sensor, visit your local mechanic, who is updated on this system and can properly install them.

Final Thoughts On TPMS

Tires are fundamental for your vehicle well performance and safety. If your car has a sensor, it is vital to keep regular checkups. 

If you have a vehicle that needs TPMS, consider the size of your vehicle and purchase according to the TPMS specs. You can find monitors that are for trucks, cars, and RVs.

Ensuring you get the ideal monitor will give you more control over your car.

TPMS brings many benefits, from fuel economy to a longer lifespan of your tires. This is why it is relevant to consider getting your ideal system. This system is not difficult to install, and rest assured you will be grateful for getting it.
