What Are The Primary Reasons For Car Tyre Cracking?

The design, production and innovation of tyres date way back than you can think. The tyre producers have always attempted to innovate tyres that would last longer, and better and would fulfil the responsibility in most situations. Today, you can find tyres that are perfect for the summer season, winter season, tyres best for use throughout the year, different terrain tyres, etc. 

High engineering, innovation and top-quality equipment are crucial to producing a line of best-quality tyres. Tyres are undoubtedly one of the most important parts of a car as they are the only part that touches the ground. They are responsible for the rolling, braking, speeding, turning, etc of the car. So, the rubber compound causes friction when touches the ground. 

And friction for a longer period can cause damage to a product. So is the case with the tyres. It suggests that no matter how hard you try, your Car Tyres Wolverhampton won’t last forever. However, you can delay the damage with proper care and maintenance, but not forever. 

There are many tyre degradation signs that you need to look out for. And among all of them, cracking is the one. So today, we are going to know about the tyre cracks, the reason for their occurrence and the ways to fix them. Also, get to know the best place to get the best Tyres Essington.

What makes your tyres crack?

Your car tyres are strong enough to handle the weight of the whole car and the occupants inside it. Do you ever think that what makes it possible? 

Of course the various parts that are a part of the tyre composition method and the ones that form its structure. Components like piles or the fibres inside the tyre provide some flexibility to the tyre along with maintaining the structure of the tyre, the beads or the steel part that has a coating of rubber that creates a seal in between the wheel rim and the tyre. These all are responsible for it.

The rubber part on the outer area of the tyre has a composition of loads of polymers, knitted together to make molecules. And the tyre cracks are a result of breakages between these bonds. But the question is, ‘what makes these bonds weak?’

Extreme heat or UV rays

The tyre polymers tend to contract in the cold atmosphere and expand in the hot atmosphere. This can result in the weakening of the bonds after a certain period. This is when tyres get the cracks in them. UV rays also tend to have a similar effect on Mot Wolverhampton. People normally find it difficult to save their tyres entirely from the UV rays, leading to damages such as tyre cracks, etc.


It is only natural for your tyre polymers to weaken after passing a certain age limit. This results in your tyres becoming brittle and hard as the elasticity lessens. Tyres can go weak even if you don’t drive your car and keep it stored in a garage. Inactivity can still age your tyres.

Hence, keep on driving your car, even if for a little distance, rather than keeping it inactive in one place. The chemical that helps in the prevention of drying and cracking of the tyres comes out if you move the tyres.


Although rubber compounds are water-proof, it is risky to the longevity of the tyres if water gets into their interior. This generally occurs if you drive on heavily wet roads or deep potholes. 


Rubber is an organic material that comes from trees. And tyres have the primary components of rubber in them as the main ingredient. Hence, they are bio-degradable and you can’t stop them from naturally degrading even if you put in a lot of chemicals.

Some chemicals can slow down the natural degradation process but they can’t stop them from degrading forever.

Tyre pressure

Tyre pressure level plays a vital role in determining the damage level, efficiency and other factors of your tyre and overall vehicle performance. If your tyres have lesser pressure than there should be, it produces more heat due to more friction. It happens as the tyres with less pressure are more in contact with the road.

While having extra pressure on the tyres can cause bulging of the sidewalls by exerting extra pressure on the sidewalls of the tyres.

You should always keep a check on your tyre pressure level and you can do so using a TPMS.
