Top 20 Causes of Tyre Deflation and How to Prevent Them | Expert Guide
Published:

Tyre deflation can occur for many reasons, and being aware of these causes will help you maintain optimal tyre pressure and avoid unexpected road issues. Below are 20 common reasons for tyre deflation and tips on how to prevent them.

1. Leaking Valves

The valve stem can become corroded or damaged, causing air to leak slowly. Regular inspections help catch these leaks before they cause significant deflation.

2. Hitting the Kerb

Any significant impact on your tyres can lead to a puncture or structural damage. Always inspect your tyres after hitting a kerb to ensure they haven’t been compromised.

3. Vandalism

Although rare, tyre deflation caused by vandalism can occur. If you find deflated tyres without visible damage, it could be due to someone tampering with them.

4. Weather Conditions

Extreme heat can expand the air in your tyres, causing over-inflation and eventual rupture. In colder weather, air contracts, leading to under-inflation. Regular checks during weather changes are vital.

5. Tyre Bead Leaks

Leaking air from the tyre bead (the rim) can cause slow deflation. Spraying the area with soapy water will help detect tiny air leaks.

6. Punctures from Sharp Objects

Nails, screws, or debris on the road can puncture your tyres, causing a slow leak or immediate deflation. Be mindful of road conditions and avoid debris when possible.

7. Under-Inflation

Driving on under-inflated tyres increases the risk of damage and deflation. Always check your tyre pressure regularly, especially before long journeys.

8. Over-Inflation

While under-inflation is harmful, over-inflation can also lead to tyre blowouts. Stick to the recommended tyre pressure outlined in your vehicle manual.

9. Old Tyres

Tyres degrade over time, and old tyres are more prone to deflation. Inspect your tyres regularly and replace them as needed.

10. Damaged Wheel Rims

Bent or damaged wheel rims can create gaps between the tyre and the rim, allowing air to escape. If you suspect rim damage, get it checked immediately.

11. Improper Tyre Installation

Incorrectly installed tyres can result in air leaks. Ensure tyres are properly fitted by professionals to avoid deflation issues.

12. Faulty Tyre Seals

Faulty or damaged seals around the valve or the rim can lead to a slow loss of air. If your tyres are continuously deflating, this could be the cause.

13. Tread Wear

As the tread on your tyres wears down, the chances of a puncture or air leak increase. Regularly check your tyre tread depth and replace tyres when they’re worn.

14. Corroded Rims

Corrosion on your wheel rims can prevent a proper seal, allowing air to escape slowly. Clean your rims regularly to avoid this issue.

15. Improper Storage

If tyres are stored improperly (exposed to sun, heat, or cold), they can become more prone to deflation. Always store tyres in a cool, dry place.

16. Valve Cap Missing

A missing valve cap can allow dirt and moisture to get into the valve, potentially causing leaks. Always replace missing valve caps.

17. Driving on Rough Terrain

Constant driving on rough or unpaved roads can wear down tyres faster, making them more prone to punctures and deflation.

18. Sudden Temperature Changes

Sudden fluctuations in temperature, especially when transitioning from hot to cold weather, can cause rapid changes in tyre pressure. Check your tyres frequently during these shifts.

19. Damaged Suspension

If your vehicle’s suspension system is compromised, uneven weight distribution can cause excess wear on one side of the tyre, leading to deflation.

20. Tyre Age

Even if tyres appear to have adequate tread, rubber deteriorates over time. Tyres older than six years should be inspected for wear and replaced if necessary.
