Tyres are a critical component of your vehicle’s safety, ensuring grip, handling, and performance. Over time, you may notice cracks developing on the tyre’s tread or sidewall, raising the question: “Cracks in tyres—are they dangerous?”
This guide explores the causes of tyre cracking, when it becomes a safety concern, and how to address it.
What Causes Cracks in Tyres?
Cracks in tyres can develop due to several factors, including:
- UV Exposure: Prolonged exposure to sunlight degrades rubber over time.
- Age: Tyres naturally deteriorate with age, even if they’re not heavily used.
- Improper Maintenance: Incorrect tyre pressure and lack of regular inspections can accelerate cracking.
When Are Cracks a Safety Concern?
While some cracks might seem minor, they can compromise the tyre’s integrity. Here’s what to look for:
Small Cracks in Tyres
Small cracks in tyres are often a sign of early aging. Although they may appear harmless, monitoring their progression is essential.
Small Cracks in Tyre Sidewall
Cracks in the sidewall can weaken the tyre’s structure, increasing the risk of a blowout. If you notice small cracks in tyre sidewall, have them inspected by a professional.
When Are Cracks in Tire Tread Unsafe?
Cracks in the tread area reduce grip and can lead to uneven wear. Refer to a tire tread cracking chart to assess the severity of the damage.
Tyre Cracking When to Replace
If the cracks penetrate deeper than the surface layer or span a large area, it’s time to replace the tyre. Ignoring such damage can result in dangerous driving conditions.
Are Cracked Tyres Legal in the UK?
Are cracked tyres illegal? Yes, tyres with severe cracking that affects performance and safety may fail an MOT test. It’s essential to address such issues promptly to stay compliant with UK road safety standards.
How to Prevent Tyre Cracking
- Regular Inspections: Check for cracks during routine maintenance to catch early signs of damage.
- Maintain Proper Pressure: Avoid over- or under-inflating tyres, as this can contribute to cracking.
- Use Tyre Protectants: Products designed to shield rubber from UV rays can slow deterioration.
- Replace Old Tyres: Even if your tyres appear fine, replace them every 6–10 years to prevent age-related cracking.
Understanding Cracks with Charts and Guidance
Utilizing tools like a tire sidewall cracking chart or a tire tread cracking chart can help assess the damage’s severity. These resources are invaluable for understanding when cracks are superficial and when they pose a genuine safety risk.
