If you have a Tire Pressure Monitoring System (TPMS), you might think checking tire pressure manually is unnecessary. However, regularly checking your tire pressure is still essential for optimal vehicle performance and safety. TPMS serves as a helpful tool, but it has limitations and should not replace routine tire maintenance.

Why Check Tire Pressure Even with TPMS?

Understanding TPMS and Its Limitations

TPMS is designed to alert drivers when tire pressure falls below a certain threshold. However, it does not provide real-time pressure readings or detect gradual pressure loss. Relying solely on TPMS can lead to driving with under-inflated tires, affecting fuel efficiency and tire lifespan.

• Threshold Limitations: TPMS often triggers only when pressure drops 25% below the recommended level, which might already be unsafe.
• Delayed Alerts: TPMS might not alert you immediately to slow leaks or gradual pressure loss.
• Temperature Variations: Tire pressure can fluctuate with temperature changes, and TPMS may not account for these minor variations.

Benefits of Regular Tire Pressure Checks

Manually checking tire pressure ensures your vehicle’s tires are properly inflated, enhancing safety and performance.

• Improved Fuel Efficiency: Properly inflated tires reduce rolling resistance, leading to better fuel economy.
• Extended Tire Lifespan: Correct pressure minimizes uneven wear, extending tire life.
• Enhanced Safety: Proper inflation improves handling and reduces the risk of blowouts.

How to Check Tire Pressure Manually

Regularly checking tire pressure is simple and can be done in a few steps:

1. Purchase a Tire Pressure Gauge: Digital or analog gauges are readily available and easy to use.
2. Identify Recommended Pressure: Check your vehicle’s manual or the sticker inside the driver’s door for the recommended PSI.
3. Measure Tire Pressure: Remove the valve cap from each tire and press the gauge onto the valve stem. Compare the reading to the recommended PSI.
4. Adjust as Needed: If the pressure is too low, add air until it reaches the recommended level. If it’s too high, release some air.

What Does TPMS Stand For?

TPMS stands for Tire Pressure Monitoring System. It is an electronic system in vehicles designed to monitor the air pressure inside pneumatic tires and alert the driver when the pressure is dangerously low.

Can I Rely on TPMS Alone?

While TPMS is a valuable tool, it should not be relied upon exclusively. It can alert you to dangerously low pressure but might not detect gradual leaks or slight under-inflation. Regular manual checks are recommended for comprehensive tire maintenance.

How Often Should I Check Tire Pressure?

It’s advisable to check your tire pressure at least once a month and before long trips. Regular checks ensure that your tires remain at the optimal pressure for safety and efficiency.

What Are the Signs of Low Tire Pressure?

Signs of low tire pressure include a TPMS warning light, poor fuel economy, decreased handling, and visibly deflated tires. Regular checks can help prevent these issues.

Does Temperature Affect Tire Pressure?

Yes, temperature significantly affects tire pressure. Typically, for every 10°F change in temperature, tire pressure changes by about 1 PSI. It’s crucial to check tire pressure during temperature fluctuations.

Conclusion

While TPMS provides valuable alerts for dangerously low tire pressure, it should not replace regular manual checks. Ensuring your tires are properly inflated enhances safety, efficiency, and longevity. Make it a habit to check tire pressure monthly and before long journeys. By doing so, you’ll enjoy a smoother, safer driving experience.
