No, you do not automatically get new sensors when replacing tires. Tire pressure monitoring system (TPMS) sensors may need to be reused or replaced, depending on their condition.
One reason for not receiving new sensors with tire replacements is the variability in sensor longevity. Some sensors can last for several years, while others may malfunction or run out of battery. If the existing sensors are functioning well, they can be transferred to the new tires. However, if the sensors show signs of damage or are outdated, it is advisable to replace them to ensure proper tire pressure monitoring.
What Are the Different Types of TPMS Sensors Available for Tire Replacement?
The different types of Tire Pressure Monitoring System (TPMS) sensors available for tire replacement are direct TPMS sensors and indirect TPMS sensors.
- Direct TPMS Sensors
- Indirect TPMS Sensors
Understanding the differences between these two types of sensors is essential, as each serves a unique purpose and has specific advantages and disadvantages.
1. Direct TPMS Sensors:
Direct TPMS sensors actively measure the tire pressure and send data to the vehicle’s onboard computer. These sensors are typically located inside the tire, mounted on the valve stem. They provide real-time tire pressure readings. According to a study by the National Highway Traffic Safety Administration (NHTSA), direct TPMS can accurately monitor tire pressure within 1 psi of inflation levels. Additionally, many manufacturers use lithium batteries in these sensors, which can last between 5 to 10 years.
For example, a direct sensor can alert the driver if a tire loses pressure suddenly, potentially preventing accidents. These sensors require programming after tire replacement, but they offer precise monitoring, improving vehicle safety and fuel efficiency.
2. Indirect TPMS Sensors:
Indirect TPMS sensors do not measure tire pressure directly. Instead, they use the vehicle’s Anti-lock Braking System (ABS) to determine tire pressure based on wheel speed. If one tire rotates faster than others, it indicates lower pressure. While these systems are generally less expensive, they can be less accurate than direct systems.
According to tire industry expert Michael B. Smith in his 2021 article, indirect TPMS can only alert drivers about significant tire pressure dips, potentially leading to issues before the problem becomes critical. Furthermore, they require recalibration after tire rotation or replacement because they rely on wheel speed data.
Both sensor types have their pros and cons. Direct sensors are more accurate and provide ongoing monitoring, but they are more complex and often require replacement of the battery or sensor if they fail. Indirect sensors are simpler and cheaper but can miss gradual pressure changes. Understanding these differences can help drivers make informed choices when replacing tires and sensors.
When Should TPMS Sensors Be Replaced During Tire Changes?
TPMS sensors should be replaced during tire changes in specific situations. First, consider the age and condition of the sensors. If they are older than five years, it is wise to replace them.

Third, if you are using a new type or size of tire, consult the manufacturer’s guidelines. Some new tires may require updated sensors. Additionally, when you replace the tires, it is a good opportunity to ensure the sensors are calibrated correctly. Calibrated sensors provide accurate pressure readings. Overall, replace TPMS sensors if they are old, damaged, or if compatibility with new tires is in question.
How Do You Identify If Your TPMS Sensors Need Replacement?
You can identify if your Tire Pressure Monitoring System (TPMS) sensors need replacement by observing warning lights, checking tire pressure readings, and noticing sensor malfunctions.
A warning light on your dashboard is often the first indication that something is wrong with your TPMS. This light typically resembles a flat tire or the letters “TPMS.” If this light is illuminated persistently, it may indicate a malfunction in one or more sensors.
Additionally, you should check tire pressure readings. If the display shows abnormal values, such as a constant reading of zero or unusually high or low pressures, it may indicate that the sensors are failing. Studies show that faulty TPMS sensors can lead to unsafe driving conditions due to improper tire pressures (AAA Foundation for Traffic Safety, 2021).
Malfunctions in sensor operation also signal the need for replacement. For instance, if the warning light resets occasionally without an apparent reason or fails to respond when manually adjusting tire pressure, the sensors may be faulty. Sensors typically have a lifespan of about five to ten years or approximately 100,000 miles. Older sensors may be less reliable as they age.
Finally, if your vehicle frequently experiences issues with tire pressure alerts after new tires have been installed, it may indicate the need for new sensors. Properly functioning sensors are crucial for maintaining optimal tire pressure, which plays a significant role in safety, fuel efficiency, and tire longevity.
