Maintaining proper tire pressure is crucial for safe and efficient driving. Your car’s Tire Pressure Monitoring System (TPMS) alerts you when tire pressure is low, but what happens when the TPMS itself malfunctions or needs replacement? This raises the question: Should you replace your TPMS when getting new tires?

Understanding the TPMS
What is TPMS?
The TPMS is a system designed to monitor the air pressure in each of your vehicle’s tires. It typically consists of sensors located inside the tires that transmit pressure readings to a dashboard warning light. When pressure drops below a certain threshold, the light illuminates, alerting you to the issue.
Why is TPMS Important?
Proper tire inflation is essential for several reasons:
- Safety: Underinflated tires can increase braking distance, reduce handling stability, and increase the risk of blowouts.
- Fuel Efficiency: Underinflation can lead to increased rolling resistance, reducing your vehicle’s fuel economy.
- Tire Wear: Improper inflation can cause uneven tire wear, leading to premature tire replacement.
Should You Replace TPMS with New Tires?
The decision to replace your TPMS with new tires depends on several factors, including the age and condition of your current TPMS sensors, the type of new tires you are purchasing, and your budget.
Should I Replace TPMS With New Tires?
Your tire pressure monitoring system (TPMS) is a vital safety feature that alerts you when your tire pressure is low. But what happens when you need new tires? Should you replace your TPMS sensors as well? This article will delve into the intricacies of TPMS and tire replacement, helping you make an informed decision about your vehicle’s safety and performance.
Understanding TPMS
TPMS sensors are small electronic devices embedded within your tires that constantly monitor air pressure. These sensors transmit data to your vehicle’s dashboard, displaying the tire pressure of each wheel. When the pressure drops below a predetermined threshold, a warning light illuminates on your dashboard, alerting you to the issue. (See Also: Where To Get Tires Mounted And Balanced)
Types of TPMS
There are two main types of TPMS:
- Direct TPMS: These sensors have a battery and transmit tire pressure data directly to the vehicle’s control module. They are more accurate and provide real-time information.
- Indirect TPMS: These systems rely on wheel speed sensors to detect changes in tire pressure. They are less accurate and may not detect slow leaks as effectively.
When to Replace TPMS Sensors
While TPMS sensors are designed to be durable, they do have a lifespan. Here are some instances when you might need to replace them:
Age
TPMS sensors typically have a battery life of 5-10 years. As the battery weakens, the sensor’s performance may deteriorate, leading to inaccurate readings or the warning light staying on.
Damage
TPMS sensors can be damaged during tire repairs, accidents, or curb strikes. If you suspect your sensor is damaged, have it inspected by a qualified mechanic.
Compatibility
If you are switching to a different type of tire or wheel, the TPMS sensors may not be compatible. It’s essential to ensure that your new tires and wheels have compatible TPMS sensors.
Replacing TPMS Sensors with New Tires
When replacing your tires, it’s generally recommended to replace your TPMS sensors as well. This ensures optimal performance and accuracy of your TPMS system. (See Also: What Are Dot Tires)
Benefits of Replacing TPMS Sensors
- Improved Accuracy: New sensors provide more precise tire pressure readings, enhancing safety and fuel efficiency.
- Extended Lifespan: Replacing sensors with new tires ensures a fresh start for your TPMS system, maximizing its lifespan.
- Peace of Mind: Knowing that your TPMS sensors are functioning correctly provides peace of mind and reduces the risk of unexpected tire issues.
Cost Considerations
Replacing TPMS sensors can add to the overall cost of new tires. However, it’s a worthwhile investment considering the safety and performance benefits.
Conclusion
While TPMS sensors are durable, they do have a lifespan and may require replacement. When replacing your tires, it’s highly recommended to replace your TPMS sensors as well. This ensures optimal accuracy, extends the lifespan of your TPMS system, and provides peace of mind knowing that your vehicle is equipped with a reliable safety feature.
FAQs: TPMS and New Tires
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. It’s a safety feature in modern vehicles that alerts the driver if the tire pressure is too low.
Do I need to replace my TPMS sensors when I get new tires?
Not necessarily. TPMS sensors are usually built into the tire valve stem. Some newer sensors are transferable, meaning they can be moved from your old tires to your new ones. However, it’s best to check with your tire shop or vehicle manufacturer to confirm if your sensors are transferable and if they need to be reprogrammed.
What happens if I don’t replace my TPMS sensors with new tires?
If your TPMS sensors are not compatible with your new tires or are damaged, your TPMS warning light may stay on. This can be annoying, but more importantly, it means you won’t receive accurate tire pressure readings, potentially compromising your safety. (See Also: Will Overinflated Tires Cause Vibration)
How much does it cost to replace TPMS sensors?
The cost of TPMS sensors can vary depending on the make and model of your vehicle. Generally, you can expect to pay between $25 and $100 per sensor.
Can I install TPMS sensors myself?
While it’s technically possible to install TPMS sensors yourself, it can be tricky and requires specialized tools. It’s generally recommended to have a qualified mechanic install them to ensure proper functionality and avoid damaging your vehicle’s electrical system.
