What Are Cracked Tyres?

Cracked tyres refer to visible splits or lines that appear in the rubber. These cracks typically form along the outer surface but can worsen over time, eventually affecting your tyre’s optimal performance. Cracks are one of the most common issues found during regular tyre inspections and are particularly important to address promptly.

At Autocentres, we have seen how quickly surface damage to tyres can become a major safety concern if left unchecked. Our tyre specialists are trained to assess even the smallest signs of wear and offer the right advice for your safety.

How to Spot Cracked Tyres

Spotting early damage on your tyres can help you act before your safety is affected. Below are clear warnings that your tyres could be developing serious cracks and require your urgent inspection or immediate replacement.

• Dry, flaky rubber – Often the first sign of your ageing tyre or prolonged exposure to heat and sunlight.
• Tread blocks’ cracks – These can reduce your tyre grip and worsen with use.
• Tyre sidewall splits – These areas are under frequent pressure and weaken gradually.
• Bulges or lumps – A warning that your tyre’s internal components may be compromised.
• Irregular patterns – Uneven wear or cracking that suggests structural issues with your tyres.
• Low tyre tread depth – When combined with visible cracking, this increases your risk, especially on wet roads.

If you notice any of the above during your routine tyre inspection, it’s best to act immediately. At Autocentres, we provide professional tyre checks to help you stay safe and prevent further damage. Get in touch with us today on 01495 239 953 to drive with greater confidence in your tyres.

What Causes Cracked Tyres?

Tyre cracking is one of the most common causes of tyre damage. It develops gradually and often results from a combination of ageing, pressure changes, and road exposure. At Autocentres, we help you understand what contributes to this issue so you can take steps to protect your tyres and avoid early wear.

Ageing and Weathering

Rubber naturally breaks down over time. Exposure to UV rays and fluctuating temperatures causes your tyres to harden and lose flexibility. Cracks often appear on older tyres, especially if your vehicle is parked outdoors or used irregularly. This ageing process affects your tyre’s structure and can reduce performance in both dry and wet conditions.

Improper Inflation

Driving with incorrect tyre pressure places uneven stress on your tyre rubber. Underinflated tyres flex more than necessary, increasing friction and heat. Overinflated tyres, on the other hand, become rigid and are more vulnerable to surface cracking. Keeping to your correct tyre pressure is crucial for even wear and extending tyre life.

Prolonged Inactivity

If your vehicle is left unused for a while, your tyres can develop flat spots or surface cracks. When your car stays in one position for too long with underinflated tyres, the weight creates added pressure that can lead to damage. To avoid this, it’s a good idea to check your tyres regularly during any long periods of inactivity. It helps you keep your tyres in better condition and saves you hassle down the line.

Harsh Driving Conditions

Consistent exposure to sharp debris, rough road surfaces, or heavy loads can accelerate tyre deterioration. Aggressive driving styles, such as rapid braking or sharp cornering, also place excessive strain on your tyres, increasing the risk of cracking and tread wear.

Are Cracked Tyres Dangerous?

Even small cracks in your tyres can lead to major safety risks if ignored. What starts as a minor surface issue can quickly develop into deeper structural problems, particularly when your vehicle is exposed to ongoing pressure, heat, or poor road conditions. At Autocentres, we regularly advise drivers on the risks associated with damaged tyres and how prompt action can prevent accidents.

The loss of structural integrity in your tyres can compromise your braking, handling, and grip. Cracks can widen with continued use, reducing the tyre’s ability to respond during sudden stops or sharp turns. This puts both you and other road users at increased risk, especially at higher speeds.

In the UK, tyres must meet a minimum legal limit for tread depth and overall condition. Cracks that reach beyond the surface can be grounds for MOT failure, even if the tread appears acceptable. To stay road-legal, addressing your tyre cracks proactively is essential.

To make sure your tyres are safe and compliant, contact Autocentres on 01633 872 001 for our trusted tyre inspection service. We will assess the condition of your tyres and help you decide whether repair or replacement is your safest step forward.

Can Cracked Tyres Be Repaired, or Do They Need Replacing?

In most cases, cracked tyres cannot be safely repaired. Once your tyre’s rubber begins to split around the sidewall or tread, your tyre’s structural strength is compromised. Even if the damage seems minor, cracks can deepen gradually and affect how your vehicle handles, particularly at higher speeds or in unpredictable conditions. At Autocentres, we assess your tyre condition professionally and help you decide the safest and most efficient course of action.

Ignoring your cracked tyres can lead to serious consequences. Your weakened tyre is more likely to fail under pressure, especially during sudden braking, cornering, or when carrying heavy loads. Your risks increase significantly if cracks continue to develop without any interventions. That’s why Autocentres recommends regular tyre checks as part of your ongoing vehicle care. By identifying early signs of wear, you can avoid unexpected breakdowns and costly damage.

In most cases, tyre replacement is your safest option once cracking appears. Our experienced team at Autocentres will inspect the level of wear and provide straightforward advice based on your driving needs. We stock a wide range of reliable tyres and fit them to manufacturer standards, so you can drive with complete peace of mind.

How to Prevent Cracked Tyres

Preventing tyre cracking starts with your simple, consistent care. At Autocentres, we believe your tyres deserve the same attention as any other part of your vehicle. Your regular habits can make all the difference to your car’s performance, safety, and overall driving confidence.

Regular Tyre Maintenance

Maintaining your correct tyre pressure is vital. Underinflated or overinflated tyres increase wear and stress, leading to cracks. Regular pressure checks help preserve your tyre shape and reduce your risk of initial damage. Rotating your tyres also supports even wear, which contributes to dependable performance. At Autocentres, we offer routine tyre checks as part of our everyday service to help keep your vehicle safe and running smoothly.

Proper Storage and Protection

Where and how your vehicle is stored affects your tyres. Direct sunlight, harsh chemicals, and standing water all accelerate rubber deterioration. If your car is parked for long periods, keep it in a cool, dry area away from constant exposure. Seasonal storage during extreme weather should include your tyre protection to minimise long-term damage.

Driving Habits That Help

Adopting a smooth driving style helps keep your tires in good condition. Avoiding excessive braking, harsh cornering, and uneven acceleration reduces strain on your rubber and supports longer-lasting performance. Improving your habits results in enhanced driving dynamics. At Autocentres, we encourage safer, more efficient techniques to protect and extend the service life of your tyres.

FAQs:

Will Cracked Tyres Fail MOT?

The legal tread depth of your tyres should be 1.6mm. If the depth is below this, or your tyres are torn, extremely cracked or bulged, they will be deemed as unsafe and therefore will fail the MOT of your car.

Are Cracked Tyres Legal?

If your car tyre has only small cracks in it, they are still legal; however, it is a sign that your tyres are on their way out. Substantial cracks will be considered illegal, posing a risk to both you and other road users while driving.

Why Do Cracks Appear On Tyres?

Age is the main cause of the degradation of car tyres, which leads to cracked tyres. As a tyre gets older, the polymers will weaken; therefore, they start to break down. This causes a loss of elasticity, leaving the tyre brittle and eventually leading to a cracked tyre as it fully weakens.

There are factors you cannot control, such as sunlight or exposure to UV rays. This can weaken the rubber compounds in your tyres, resulting in cracking.

The conditions the tyres are performing in are also a factor. Frequent driving along uneven terrains and driving habits such as hard braking or exposure to chemicals like oil, petrol, diesel, or even cleaning solutions can result in degradation of your tyres’ compounds.

However, car owners can control several factors that affect the lifespan of their tyres. These include:

Under-inflation of your tyres – this causes an excessive bending of the tyre walls, leading to a heat build-up when driving, resulting in a weakened tyre. Conversely, overloading your tyres can cause extra stress, which may lead to tyre cracks.

When are Cracked Tyres Dangerous?

Tyres are at their most dangerous when they are cracked; the thinner the tread, the more dangerous it is. It is vital to address them properly as soon as you realise. Cracked tyres are particularly dangerous when. There are factors you should consider when looking at your tyre cracks,

• Cracks on the wall of your tyres can result in sudden tyre failure and loss of control of a vehicle.
• Size of the tyre crack: Review the depth and length of the crack
  
• Driving conditions: Cracked tyres have reduced performance, and traction and handling are affected. This may be detrimental if you are driving in wet or icy conditions.
• Long distance driving: Cracked tyres can become worse when they are put under continuous stress, the heat build-up during a long drive may worsen the cracks or lead to a tyre blow out.
