Why does a car tyre burst happen, and how to prevent it?


The rapid loss of pressurised air from the tyre causes a tyre to burst. When the tyre’s structural integrity is weakened, it cannot keep any of the air insides. Pressurised air escapes by quickly ripping through the tyre, resulting in an explosion and extensive damage to the tyre surface. Buy high-quality car tyres in Hawkesbury to avoid tyre bursting. Let us take a look at the possible causes of this occurrence.

Direct impact
We have prepared ourselves and our reactions to avoid barriers, bumps, and potholes on the road through practice, but they are often unavoidable. When you hit an unavoidable obstacle on the lane, the resulting impact has a high chance of slashing the tyre surface at some stage. This slash is an open invitation for pressurised air to escape, causing a tyre to burst.

High temperatures
Heat is bad for almost everything in your car, particularly the tyres. Excessive heat build-up on your tyres is a sure-fire way to cause a tyre explosion. Heat builds up within the tyres, causing the air to become hotter, pressurised, and this leads to a tyre burst. Furthermore, friction between the road surface and the tyre causes the rubber to soften and become hotter from the outside. 

Under inflation
Inadequate air pressure in the tyres is the most common cause of a tyre explosion. Though over-inflation is not a problem, a study says that under-inflation is the cause of 75% of tyre burst-related accidents. Excessive flexing occurs in under-inflated tyres, which will invariably increase your contact patch with the road. This causes an increase in frictional force and, as a result, excessive heat build-up inside the tyre. Keep in mind that a tyre burst due to under-inflation is much greater than the risk of a tyre burst due to increased temperature.

High speed
Each tyre on the market is rated for a specific speed at which it is intended to work properly. The materials and structure of the tyres are designed to withstand speeds only up to a certain point. Anywhere after that, the tyre structure will be unable to handle the increased friction and will soon lead to tyre explosion. The cause of tyre burst, in this case, would be due to a combination of factors, including heat generated by friction and structural limitations. As a result, the risk of incidence is extremely high in this situation.

Overloading the car
Overloading the car can cause the tyre to burst in the same way that under-inflated tyres can. Excess weight in your car will move the entire load to the rim, i.e. the tyres, causing sidewall flexing. The series that follows is identical to what occurs when tyres are under-inflated.

Ways to prevent tyre burst

Here are a few ways in which you can prevent your tyre from bursting.

Choose branded tyres
Big brands have their R&D centres, where each product concept is carefully designed and thoroughly tested before being launched. It is important to find good quality branded car tyres in Hawkesbury. They are also homologated by reputable organisations that certify the quality of these goods. Unknown brands or knock-off would almost definitely not be treated the same way, and it is best if you avoid them. 

Ensure the condition of the tyres
A tread wear indicator bar is mounted on all tyres to indicate when they should be replaced. The tread depth should ideally be 1.5mm. If the tyre is worn out, the indicator bar can become smaller and overlap with the rest of the tyre. In this case, replace the tyre as soon as possible. If your car tyre is in that condition, you can also drive at a slower pace.

Maintain air pressure
One of the main common causes of tyre burst is under-inflation. Tyre pressure rises in hot weather and falls as the temperature drops. So keep an eye on the environmental conditions around you. Maintain the recommended tyre pressure as stated in your car owner’s manual, and everything should be fine.

Avoid overloading
Putting six people and individual bags of luggage in your tiny hatchback is a bad idea. Each car is only capable of carrying a certain amount of weight. If you stick to that cap, you will not have any problems.

Note tyres speed rating
The tyre’s speed rating is listed next to its dimensions on the sidewall. Based on the prescribed load index on your tyre, the tyre speed rating is the highest speed that the tyre is legally allowed to be driven. These speed ratings are based on real-world testing that engineers conduct when designing new tyres to ensure that they can safely achieve high speeds.

Maintain driving speed
Begin by driving at a reasonable speed; there are no two ways about it. The slower you go, the better your chances are of surviving. At 80-90 kph, a blowout would be much less dramatic than at 140-150 kph. Consider it as a blessing from God if you survive a tyre burst at 150 kph.

Maintain the tyres
Well-maintained tyres will save lives. Make sure your tyres are in good condition. The tread depth should be optimum. On the sidewalls, there should be no bulges or cuts. A tyre’s lifespan is usually six years. Regardless of the miles driven, a tyre older than six years should be replaced.

Wrapping it up
A lack of car maintenance can cause tyre bursts or blowouts, so testing and changing the tyres regularly is important. Avail of the good quality car tyres in Hawkesbury, which ensures the safety of the tyres. Hence, the details mentioned above will help you know the cause and preventive measure of tyre burst.
