  • Hot Weather: Conversely, as temperatures rise, tire pressure increases.
• TPMS Sensitivity:
  • TPMS is designed to alert drivers when tire pressure falls below a certain threshold. Cold weather can cause tire pressure to drop below this threshold, triggering the TPMS light.
• Accuracy Variations:
  • Extreme temperatures can affect the accuracy of TPMS sensors. The sensors may provide slightly different readings under very hot or very cold conditions.
• Seasonal Adjustments:
  • It’s important to check and adjust tire pressure seasonally to account for temperature changes. Adjust tire pressure in the morning when tires are cold for the most accurate reading.
• Nitrogen Inflation:
  • Using nitrogen instead of air to inflate tires can reduce pressure fluctuations due to temperature changes, as nitrogen is less affected by temperature variations.
• TPMS Calibration:
  • Some advanced TPMS systems can be calibrated to account for temperature changes. Consult your vehicle’s owner’s manual for calibration procedures.
• Regular Monitoring:
  • Regardless of the weather, regularly monitor your tire pressure to ensure it remains within the recommended range.

Understanding these effects ensures accurate tire maintenance and TPMS functionality.

10. Is It Safe to Drive with a Malfunctioning TPMS?
