Why do tyres burst in summer

Not only can experiencing a tyre blowout be extremely unsettling, but it can also be very dangerous for drivers, passengers and surrounding vehicles. So, how can you prevent tyre bursts from happening? And what causes tyres to burst more in the summer? Our detailed guide has you covered - answering all your tyre blowout queries.

What causes tyre burst in the summer?

So, why do tyres burst more in the warmer months? Some of the most common causes of tyre bursts in summer are:

• Tyre pressure - if your tyres are underinflated, this can cause your tyres to overheat, which increases the likelihood of tyres bursting. Ensuring your tyre pressure is correct before you head off, especially on long journeys, is important to prevent tyre burst.
• Warm temperatures - the main reasons why tyres may burst in the heat is due to the warm temperatures combined with the above point of underinflation. This combination is especially dangerous - as the bonds in an underinflated tyre are more likely to break down in the heat, which can lead to a tyre burst tyre.
• High speeds - if you're travelling at high speeds and the weather is warm, this can also cause tyre bursts - especially if your tyres are underinflated.
• Old tyres - wear and tear in tyres is common, but the friction created between the road surface and tyre on a warm day can weaken the rubber - which can easily lead to a burst tyre.
• Impact - external factors such as dips, bumps and potholes in the road, can also lead to tyre blowouts - especially if you travel over these high impact obstacles at high speed.
• Heavy load - the amount of weight you're carrying in your vehicle can also have an effect on tyre blowouts. Having additional passenger weight and luggage is likely to put more pressure on the tyres - and could result in a burst tyre.

How to prevent tyre burst

• Tyre pressure - ensure your tyre pressure is correct, and your tyres are properly inflated.
• Reduce heavy load - keep your vehicle weight to a minimum in warm temperatures to avoid excess pressure on tyres.
• Tread depth - checking your tread depth matches the legal requirement will also help ensure your tyres are as safe as they can be to avoid tyre bursts.
• Speed rating - when you buy your tyres, select a tyre with the most applicable tyre speed rating.
• Reputable tyre brands - choose from trusted tyre manufacturers to ensure your tyres are as safe as they can be.
