A tyre blowout is understandably one of the scariest and most dangerous things that can happen while you’re behind the wheel. It’s therefore incredibly important to understand what can cause a tyre blowout so you can do everything in your power to prevent it, protecting not only yourself and your passengers, but other road users too.
The problem: As with most things, ageing tyres lose their strength and integrity. Even if they look in good condition on the outside, the rubber inside is likely to be deteriorating and unsafe.
The solution: We recommend that if your tyres are 6+ years old, they will need replacing, even if they look fine on the outside.
The problem: Having underinflated tyres is the biggest cause of blowouts. As there’s less pressure in the tyre, more of its surface comes into contact with the road which increases friction. The friction heats up the tyre to such a level that the tyre weakens and, eventually, blows.
The solution: Use a pressure machine found at most petrol stations to regularly check the pressure of your tyres, especially before long journeys. You can find the correct tyre pressure in your car’s manual.
The problem: Long journeys put your tyres under a lot of pressure and the friction between the tyre and road surface causes them to heat up in a similar way to under underinflated tyres.
The solution: Don’t drive continuously for too long. Make sure you take a break every few hours or so and allow enough time for your tyres to cool down. This has the added bonus of letting you stretch your legs and refuel yourself.
The problem: Bald tyres means the tread on the tyre has worn away to such a degree that it no longer provides enough grip to stick to the road surface. As well as an increased risk of skidding and an increased breaking distance, this thinning also means there is a higher risk of the tyre blowing out, especially when travelling at high speeds.
The solution: Check the tread of your tyres regularly to ensure they are at a safe level. If you find the tread has worn away, get new tyres immediately.
The problem: Usually made worse when tyres are underinflated, overloading your car puts extreme pressure on your tyres that they weren’t designed to withstand. In extreme cases this will cause the tyre to blowout.
The solution: Firstly, make sure your tyres are at the correct pressure and secondly, check the max weight your car can withstand. Again, this can be found in your vehicle’s owner manual.
If your tyre does blow out, try to remain calm, keep a firm grip on the steering wheel and do not apply the brakes unless you need to, in which case apply very light pressure (do not slam on the breaks!). Pull over as safely as possible and put your hazards on. If you’re in a safe enough place change the tyre or call roadside assistance or a local garage for professional help.
