Cracks in your tyres might appear insignificant at first glance, but they can indicate serious issues that jeopardise your safety on the road.
Identifying and preventing these damages is essential for maintaining optimal vehicle performance and ensuring a secure driving experience.
What are Tyre Cracks?
Tyre cracks are fissures or splits that develop on the surface of a tyre, commonly appearing on the sidewall or within the tread depth. These cracks occur due to factors such as ageing rubber compounds, environmental damage from exposure to extreme temperatures and UV radiation, incorrect tyre pressures, and prolonged periods of inactivity.
Over time, tyre rubber becomes hard and brittle, making it susceptible to cracking. This weakens its structural integrity, increasing the risk of a blowout and potential loss of control on the road.
Factors That Cause Cracking Tyres
Several factors contribute to tyre cracking. While some are unavoidable, others can be minimised through proper maintenance:
Age
Over time, the rubber compounds in tyres naturally deteriorate, becoming hard, brittle, and prone to cracking. This ageing process is further accelerated during long periods of inactivity.
Weather Conditions
Extreme temperatures, UV radiation, and moisture can all damage tyres. Heat causes the rubber to expand, while cold makes it contract, leading to stress and eventual cracking. UV rays degrade the rubber compounds, and water can seep into existing cracks, causing further damage—especially if it freezes and expands.
Tyre Pressure
Incorrect air pressure, whether too low or too high, can lead to cracking. Under-inflation causes increased contact with the road, which in turn, causes more friction and heat buildup. Over-inflation may cause bulging and weaken the tyre, increasing the risk of a blowout.
Preventing and Managing Cracked Tyres
To reduce the risks associated with cracked tyres, consider the following steps:
- Regular Inspections: Every two weeks, thoroughly examine your tyres for cracks, bulges, or other signs of wear. Cleaning them with soap and water can help reveal hidden damage.
- Maintain Proper Tyre Pressure: Consistently check and adjust your tyre pressure according to the recommendations in your vehicle’s handbook.
- Protect from the Elements: Whenever possible, park in a garage or shaded area to minimise exposure to direct sunlight and UV rays.
- Avoid Extended Inactivity: If the vehicle won’t be used for a while, take it for short drives every few days to keep the tyres flexible and prevent drying out.
- Replace Cracked Tyres Immediately: Cracked tyres cannot be safely repaired. Replace them promptly, using a spare tyre if necessary to reach a service centre. For balanced wear and handling, consider replacing tyres in pairs.
Where Cracks Appear
While tyre sidewalls are a common area for cracks due to their visibility, cracks can also develop in the tread. Tread cracks are less common but more concerning, as they may indicate internal rot or structural damage. Immediate professional inspection is crucial if tread cracks are detected.
Conclusion
Ensuring the safety and longevity of your tyres is essential for a smooth and secure driving experience. Regular maintenance, proper tyre pressures, and timely replacements can significantly reduce the risks associated with cracked tyres.

FAQ
What causes tyre cracking, and how can I prevent it?
Tyre cracking is caused by age, environmental damage, incorrect tyre pressures, and prolonged periods of inactivity. Regular checks, maintaining correct pressures, and avoiding exposure to harsh environmental factors like UV rays can help prevent cracks in the tyre wall and tread.
Is it safe to drive with visible cracks on the tyre and in the tread depth?
No, driving with cracked tyres can lead to a blowout and loss of control, especially on wet roads. It’s crucial to replace damaged tyres to ensure your safety.
How often should I perform a tyre check to avoid tyre blowouts?
Conduct a thorough check regularly from time to time. Inspect for cracks, ensure correct pressures, and verify that the tread depth meets the legal minimum to prevent tyre blowouts and maintain safety.
Can a prolonged period of non-use cause tyre damage?
Yes, tyres require constant movement to prevent drying out. A prolonged period without use can lead to tyre cracking. Regularly driving your vehicle helps maintain tyre integrity, whereas occasional inspections will minimise safety issues.
