What causes a tyre to burst?
There are a variety of reasons for why tyres can burst, the main causes being:
A) Driving with low tyre pressure or carrying too heavy a load: If this continues for long periods it can lead to excessive flexing of the tyre sidewall which in itself can result in overheating and premature tyre wear. The tyres can eventually no longer cope and suddenly the tread just disintegrates and / or the tyre bursts.
B) Driving over obstructions or up against a kerb or through a pothole: The external impact can result in immediate, visible tyre damage such as bulges or cracks in the sidewall or it can cause internal damage
1. Stay calm – this might be a ridiculous thing to say given the situation, but in order to make the event of a tyre burst as safe as possible
2. Keep a firm grip on the steering wheel – the car will want to pull in the direction of the burst tyre, so it is important you hold the wheel firmly with both hands to keep the car as straight as possible.
3. Do not turn onto the shoulder of the road until you have your vehicle under control – if the burst causes your vehicle to swerve onto the shoulder, do not try to get back onto the carriageway. Let the vehicle coast to a stop.
4. No heavy braking – pretty much any driver encountering a tyre burst for the first time, will want to instinctively put their foot hard on the brakes. This is one of the worst things you can do as hard braking can exaggerate the way the car wants to pull as a result of the blowout, potentially leading to an accident
5. Try your level best to keep the vehicle pointed straight – cornering or turning with a blown tyre will greatly upset the car’s composure. If your car is pulling to one side, you might need to pull the steering in the opposite direction to keep it going straight. This is critical, else you risk drifting into the road divider or worse still, the opposite lane.
6. Do not attempt to overcorrect – sharp movement of the steering wheel can result in a rollover. Even when you have gained control and are slowly moving to a safe parking spot, do so with the mildest steering inputs possible.
7. Allow the vehicle to gradually coast to a stop – use engine braking if necessary and lightly engage the brakes only when your car has decelerated to a slow speed. Use the turn indicators and pull over safely off the road.
8. Pull over safely – as soon as safely possible, pull your car over to the side of the road and put your hazards on. Ensure that
