Monitoring your Spare Tyre's Tyre Pressure with Promata TPMS
Spare tyres often go unnoticed until the moment they’re needed most. Whether you’re dealing with a flat tyre or preparing for a long trip, ensuring your spare tyre's pressure is properly monitored and integrated with your Pomata Tyre Pressure Monitoring System (TPMS) is crucial. This blog will guide you through everything you need to know about spare tyres, including how to check if you have a sensor paired to the spare tyre, pairing a sensor to the spare tyre position, and how to adjust pressure thresholds for your spare tyre.
Checking If You Have a Sensor Paired to Your Spare Tyre Position
The first step in managing your spare tyre with TPMS is understanding whether a sensor is already paired with it. Here’s how you can check:
- Switch to the Spare Tyre View on Your Display: Promata TPMS have a distinct view for the spare tyre position. On the display unit, navigate to the "Spare Tyre View" by pressing the "-" (minus) button to cycle to the spare tyre section.
- Look for Data Transmission: If a sensor is paired with the spare tyre, you will see pressure data specific to that tyre displayed on the screen. If no data appears, it likely means no sensor is paired.
- Physical Inspection: If you’re unsure about the pairing status, inspect your spare tyre for an external sensor (attached to the valve stem) or consult your vehicle’s service records to verify if an internal sensor is installed.
Pairing a Sensor to the Spare Tyre Position
If you discover that your spare tyre sensor is not connected to the display, pairing a sensor is essential. Follow these steps:
- Enter Sensor Pairing Mode: Press the settings button on your TPMS display five times. A beep sound will confirm that the system has entered Sensor Pairing Mode.
- Select the Spare Tyre Position: Use the "+" or "-" buttons to scroll through tyre positions on the display until the spare tyre position is highlighted.
- Pair the Sensor: Ensure the sensor is installed. For external sensors, simply check the spare tyre’s valve stem. For internal sensors, they will need to be installed inside the tyre. Once the sensor is in place, deflate or inflate the tyre until you hear a beep and see a pressure reading, indicating that the system has recognised the sensor.
- Save and Exit: To finalise the pairing, hold the save button on the TPMS display until you hear two consecutive beeps. The spare tyre sensor data should now appear in the "Spare Tyre View."
Adjusting the Pressure Threshold for Spare Tyres
Spare tyre pressure thresholds follow those of the caravan. Specifically, spare tyre 1 follows the trailer front axle and spare tyre 2 follows the trailer rear axel. Adjusting the pressure threshold for your spare tyre ensures accurate monitoring. Here’s how to do it:
- Access the Settings Menu: Enter settings mode by holding the settings (cog) button until you hear a 'beep'.
- Function Settings Rotation Short press the settings button three times to rotate to the "HI" front car axle pressure alarm. Continue to press the cog to rotate through Hi/Low front/rear car/trailer until you get to the appropriate axle.
- Set Custom Pressure Limits: Press "+" or "-" to choose the desired pressure threshold
- Save the Settings: Confirm the changes by long pressing the settings button. The display should now reflect the new limits for the spare tyre.
Using the Spare Tyre (Tyre Swap)
When it’s time to use your spare tyre, sensor swapping becomes critical for accurate TPMS monitoring. Depending on the type of sensor, follow these guidelines:
- For External Sensors:Simply unscrew the external sensor from both tyres and attach it to each other tyre’s valve stem.
- For Internal Sensors: Use the TPMS’s “Tyre Swap” function. Access the settings menu by holding the settings (cog) button until you hear a 'beep'. Short press the cog until you see "C1". Navigate to a tyre to swap by pressing "+" or "-" and confirm with the settings button. Next it will flash "C2" and navigate to the other desired tyre to swap. Confirm with the settings buttona and exit settings by long pressing the settings button a 'beep'.
- Adjust Pressure Thresholds: Make sure the spare tyre’s pressure matches the recommended PSI listed in your vehicle manual. Update the pressure thresholds through the front and rear trailer axel settings as mentioned above.
Important Considerations for Spare Tyres
- Sensor Placement Restrictions: Spare tyre sensors are dormant, so make sure when using the spare tyre that you, for external sensors, swap the sensors or for internal sensors use the tyre swap feature.
- Re-pairing After Deletion: If you have previously deleted a sensor from the spare tyre position, it can be re-paired by following the pairing steps outlined above. Ensure that the system recognizes the sensor after re-pairing.
- Unclear Instructions: If the instructions in this blog are unclear view the instructions in your physical manual or view the manual online available at the bottom of the blog. Additionally, if they are still unclear, view our youtube tutorial videos which can be found here or on each product's product page.
Why Monitoring Your Spare Tyre Matters
Spare tyres are often overlooked, but they are a vital part of your vehicle’s safety system. A spare tyre that is underinflated or overinflated can compromise your safety in critical moments. By integrating your spare tyre into the TPMS and keeping it properly monitored, you ensure it’s ready for use whenever needed.
Conclusion
Managing your spare tyre effectively with a TPMS system is simple and highly beneficial. From checking for paired sensors to pairing and setting pressure thresholds, these steps ensure that your spare tyre is as reliable as your regular tyres. With Promata’s advanced TPMS solutions, you can stay confident that every tyre on your vehicle, including the spare, is monitored and maintained for optimal performance.
