Introduction to Tyre Pressure Monitoring Systems (TPMS)

Understand your TPMS warning. Learn why your tyre pressure warning might be active after a tyre replacement.

Tyre Pressure Monitoring Systems (TPMS) are essential components in modern vehicles, designed to monitor the air pressure inside pneumatic tyres. These systems alert drivers when tyre pressure drops below the recommended level, ensuring the safety and efficiency of the vehicle.

How TPMS Works

The TPMS operates through sensors installed either within the tyre or as part of the valve stem assembly. TPMS operation: Direct TPMS sensors continuously measure the internal pressure of each tyre, while indirect TPMS systems infer pressure based on wheel speed. If a tyre’s pressure falls below a pre-set threshold, the system triggers a warning light on the dashboard, alerting the driver to address the issue promptly.

Importance of Maintaining Proper Tyre Pressure

Maintaining the correct tyre pressure is vital for several reasons:

  • Safety: Proper tyre pressure provides better stability, handling, and braking performance. Under-inflated tyres are prone to blowouts and can cause accidents, while over-inflated tyres reduce traction and handling capability.
  • Fuel Efficiency: Correctly inflated tyres reduce rolling resistance, improving fuel economy. Under-inflated tyres increase fuel consumption as the engine works harder to overcome the additional friction.
  • Tyre Longevity: Properly inflated tyres wear more evenly, extending their lifespan. Both under-inflation and over-inflation lead to uneven tyre wear, resulting in premature tyre replacement.

Common Occurrence of Warnings After Tyre Changes

It is not uncommon for the TPMS warning light to remain active or trigger shortly after a tyre replacement. Several factors can lead to this occurrence:

  • Sensor Relearning Process: New tyres may require TPMS sensors to be recalibrated, as recommended by the vehicle manual, but it is not strictly necessary in all cases. Failing to perform this step can result in inaccurate readings and persistent warnings.
  • Incorrect Tyre Pressure: New tyres must be inflated to the manufacturer’s recommended pressure, which may differ from the pressure needed for worn tyres. Over-inflated or under-inflated tyres can trigger the TPMS warning.
  • Faulty or Damaged Sensors: During the tyre replacement process, sensors can be accidentally damaged or improperly reinstalled, leading to erroneous pressure readings.
  • Software or System Glitches: Occasionally, the TPMS system may experience software glitches or errors that require a reset or update to resolve.

A thorough understanding of TPMS is the first step in ensuring that your vehicle operates safely and efficiently. With proper knowledge, you can address and resolve the common warnings that emerge after tyre replacements.

Sensor Relearning Process

Explanation of TPMS Sensor Relearning

Tyre Pressure Monitoring Systems (TPMS) require periodic recalibrating, especially after tyre changes, to function correctly. This recalibration process, known as sensor relearning, is integral to ensuring that each sensor is accurately monitoring tyre pressure and relaying precise information to the vehicle’s computer. TPMS sensors are typically located within each tyre and communicate wirelessly with the vehicle’s internal system to notify drivers of tyre pressure conditions.

Need for Recalibration After Tyre Changes

When new tyres are installed, TPMS sensor relearning becomes essential because the sensors might have been disturbed or replaced. Recalibrating the sensors allows the vehicle’s computer to recognise and correctly interpret data from each individual sensor. Without this step, the vehicle may not accurately track which sensor correlates with which wheel, leading to potential misreadings.

Possible Issues if Relearning is Not Performed

Ignoring the sensor relearning process can result in significant issues:

  1. Persistent Warnings: One common symptom is the continual activation of the TPMS warning light, signalling potential tyre pressure problems even if the tyres are correctly inflated.
  2. Incorrect Data: Without relearning, the vehicle may misinterpret the data from the TPMS sensors. Incorrect pressure readings can occur, causing inconvenience and alarm for the driver.
  3. Reduced Efficiency: Driving with miscalibrated TPMS can reduce the efficacy of the system, undermining one of its primary purposes—ensuring optimal tyre pressure for safety and efficiency.
  4. False Security: Drivers may falsely believe their tyres are in safe condition when the system has not been accurately recalibrated, posing potential hazards.

Maintaining an accurate TPMS through the relearning process is not merely a technical necessity but a vital aspect of vehicular safety. This recalibration ensures that the vehicle’s monitoring systems work harmoniously to provide timely and accurate information about tyre pressures, contributing to overall driving safety.

By adhering to the recalibration process after every tyre change, drivers can mitigate the risks of inaccurate tyre pressure readings, avoid unnecessary warnings, and promote longer tyre lifespan and vehicular efficiency. This brings us to the importance of ensuring the correct tyre pressure post-installation, which forms the next crucial step in maintaining a safe and efficient TPMS.

Variations in Recommended Pressure for New Tyres

Not all tyres are created equal, and neither are their pressure requirements. The recommended pressure can vary significantly based on several factors:

  • Tyre Size: Different tyre sizes require different pressures to perform optimally.
  • Vehicle Load: Heavier vehicles or those carrying heavy loads need higher tyre pressures.
  • Seasonal Changes: In colder temperatures, air contracts, leading to lower pressure. Conversely, it expands in hot weather, raising the pressure.

It is crucial to consult the vehicle’s manual or the information placard on the driver’s side door to determine the correct pressure for your specific tyres.

Effects of Over-Inflation or Under-Inflation

Incorrect tyre pressure, whether too high or too low, can lead to a myriad of issues:

  • Over-Inflation: This may result in a harsh ride, reduced traction, and uneven wear, focusing more on the centre of the tread. In extreme cases, it can increase the risk of a blowout.
  • Under-Inflation: Tyres that are under-inflated create more friction and heat, resulting in premature wear, especially on the tyre edges. This not only impacts performance and fuel efficiency but also heightens the risk of tyre failure.
