How the heat can damage your tyres

How the heat can damage your tyres 26th June 2014

Driving in summer does not come without risks to the condition of cars and tyres are one of the areas that could suffer in the heat.

The rising temperatures coupled with speed and heat build-up can all come together to weaken tyres and result in damage or, at worst, a blowout.

When the car is on the road, heat will be generated inside the tyres and can cause tyres to overinflate. This will then place stress on the rubber to steel bonding and belt package and can cause it to weaken. It can also lead to the separation and breakage of cords.

The reason why stress on a set of tyres is increased is because it constantly changes as it rolls, seeing a deflated state when in contact with the tarmac and released when it comes away. If the deflated state is significantly different to the released state then this can put stress on the internal components of the tyre, particularly as it contributes to a build-up of heat. This is made worse when the tarmac is hot.

Therefore, it is more crucial than ever during summer to make sure that drivers are frequently ensuring their tyres are in good condition.

For one thing, drivers should look over their tyres for wear and tear, such as bumps or bulges in the side walls and how deep the tread is.

They can also decrease the amount of stress caused to their tyres by ensuring that the air pressure in the tyres are correct. Following the manufacturer's guide, they should ensure that their tyres are neither under or over inflated. This will help to decrease the build-up of heat in the tyres as it lowers friction.

During the summer months it is well worth booking in for a tyre safety check now and again as expert technicians can do this for free, allowing drivers to find out if their tyres are safe to use or roughly how long they have before they need to be changed.
