Tyre burst, known to be a deadly occurrence is the phenomenon when the air is released almost instantaneously due to damage. This varies from a tyre puncture where the air is slowly and continuously released over a long period of time. Even with the continuous improvement in technology tyre blowout or burst continues to be an extremely high risk as the driver can totally lose control of the car and in certain SUVs can even lead to upturning.
What are the reasons for Tyre burst?
Tyres can burst or pop because of multiple reasons. Here is a discussion of the most common reasons:
Over or under inflation: The most common reasons for this occurrence. Inflating tyres below or above the recommended pressure causes it to bulge below leading to higher surface contact and consequently greater friction. Thus creating a high potential for burst.
Driving at speeds higher than tyre capability: When the vehicle is run on speeds that are above the limit, the tyre can rip and blow out. To know the allowable speed read the coded market on the sidewall.
High load on vehicle: If the car or vehicle is overloaded the bulge of the rubber may again lead to burst due to higher friction.
Used tyres: Second-hand tyres though providing a cheaper option, more often than not offer a much higher risk of a blowout. They, being already run on, leads to their resistance and integrity being vastly compromised.
Obstructions: Potholes, sharp objects are all too commonly encountered in our country. So while a small pierce can lead to a puncture, contact with a large obstruction can lead to the high impact on your tyre and cause it to burst
Vehicle tricks: Stunts like wheeling and such can have a bad impact on your tyres. While they might be fun and attract a lot of attention the after effects can lead to a tyre blowout
Why does tyre burst in summer?
During the summer, two things happen to your tyre:
- The construction material, a rubber polymer becomes softer. This loss of material definition can lead to the consequence of blowout easily.
- Another thing that happens is that air expands at high temperatures. This leads to the tyres being overinflated most of the time. Consequently, a greater percentage of surfaces is in contact with hot roads most of the time.
Note: These and the fact that the tyre experiences heightened temperature from within as well as from outwards lead to tyre bursting.
Do tubeless Tyres burst?
Yes, tubeless tyres do burst. When the internal pressure rises to a point that it can exert stress on the casing above its handling capability, the tyre will burst. Whether it is Tubeless or with tube does not have any effect.
What should you do if your tyre blows out while you are driving?
If your tyre blows out while driving these are the steps,
- It is crucial that you remain calm and do not panic. While it is a scary consequence, it can be handled easily
- Hold steering strongly and maintain a safe speed
- Do not brake suddenly. This is vital.
- Slow down by gradually decelerating and move towards the edge of the road
- In case a vehicle is pulling in any direction don’t try to overcorrect
- Once the vehicle has coasted to a very low-speed stop at the side
- Ensure you switch on your emergency light and use reflectors once you have stopped
If the damage is limited to the rind area and not the sidewalls, there are good chances that you will be able to repair it. In case of catastrophic damage, you will have to buy a new set.
What should you do when a front tyre bursts?
- When the front tyre bursts, the vehicle will swerve strongly in that direction.
- Hold the steering wheel to resist the pull and remove your leg from the accelerator.
- Do not jam the breaks. Once the vehicle has slowed down enough, move towards the side of the road and stop.
- Stop so that you have enough space to change it but are not a hindrance to oncoming traffic.
What happens when you have a rear tyre blowout?
When the rear burst you will feel it through the imbalance. The vehicle will deviate backwards and can even spin out of your control. Two things to maintain at this point are the direction as well as momentum.
- DO NOT break immediately as this will cause the vehicle to lose grip. Maintaining the direction may require rotating the wheel in the opposite direction.
- Press and leave the accelerator to attempt to slow down the vehicle without losing momentum.
- Once you have reached to an almost halt, find a suitable location to come to a complete stop so that you can change to the spare comfortably.
How to prevent tyre burst?
Being the number one cause of road accidents, it is no secret that tyre blowouts kill. Some useful ways to prevent these incidents are
Good tyre maintenance: Ensure they are in perfect shape all the time. This includes adequate tread depth, an absence of any bulge and damages on top as well as the side. Tyres must be ideally changed every 5 years or every 30000 km.
Fill air regularly: Maintaining the certified tyre pressure in your tyres is extremely important. You should check the pressure before you ride 5 km. this is to ensure accurate reading as it has to be cold.
Drive responsibly: Driving within the rated speed and load limit is crucial to maintaining its integrity. These are recommended based on multiple test runs to ensure optimum efficiency. Respect the rating as well as road speed limits, because these are generally based on the road. For example, concrete roads get hot very fast hence lesser speed is allowed to protect your tyres.
Avoid buying used or cheap tyres: In most cases, the quality will be compromised. Used units whose history is unknown and Chinese tyres of unknown brands not only hinder performance but also create a safety hazard.
Avoid bad roads: Roads which are not uniform put a lot of stress on your tyres. Even on highways ensure you avoid obstacles like reflectors. Stopping frequently during highway travel can help cool down your tyres.
To conclude, while it is good to be aware of the dangers of the incidence of this event, as discussed above it is possible to handle the situation. The most important of all the factors is probably the instruction to remain calm. A confident and composed driver is all that is required to protect both the passengers as well as the vehicle from tyre burst.
