Tyre bursts are one of the most dangerous on-road emergencies a driver can face. Not only do they put the vehicle at risk, but they also endanger the lives of passengers and others on the road. Understanding a car tyre burst can help you avoid such terrifying experiences.
In this guide, we’ll explore what causes car tyre bursts, how to prevent them, and what you must do if one occurs, especially in harsh summer conditions like those in Pakistan.
What Causes Car Tyre Bursts?
Several factors can lead to a tyre burst. Some are due to negligence, while others are environmental or mechanical. Here are the most common causes:
1. Under-Inflation
Driving on tyres with insufficient air pressure increases friction between the tyre and the road. This causes excessive heat buildup, especially in summer, leading to a tyre burst.
2. Over-Inflation
On the other hand, over-inflated tyres can’t absorb shocks properly and are more likely to burst upon hitting potholes or sharp objects.
3. Worn-Out Tyres
Tyres with worn treads or visible cracks are a ticking time bomb. The less tread a tyre has, the more susceptible it is to punctures and bursts.
4. High-Speed Driving
High speeds increase tyre temperature and pressure. Combined with road imperfections, this puts extra stress on the tyre walls, potentially causing a burst.
5. Overloading
Exceeding the load capacity of your vehicle puts excess weight on the tyres. This is a common issue on Pakistani highways where vehicles are often overloaded.
6. Poor Road Conditions
Broken roads, potholes, and debris can easily damage tyres, especially when combined with high speeds.
7. Manufacturing Defects
Though rare, a defective tyre from the manufacturer can also lead to sudden bursts. Always buy tyres from reputable brands and dealers.
How to Prevent Tyre Burst from Happening?
Prevention is always better than dealing with a burst tyre on a busy road. Here’s how you can avoid such emergencies:
1. Regular Pressure Checks
Check tyre pressure at least once a week, and before every long journey. Refer to your vehicle’s manual for the recommended PSI.
2. Avoid Overloading
Respect your vehicle’s load limits. Don’t use it as a goods transporter unless it’s designed for that purpose.
3. Inspect Tyres Frequently
Look out for visible signs of damage like cuts, cracks, or worn-out treads. Replace old tyres on time.
4. Drive at Safe Speeds
Avoid aggressive driving, especially over potholes or speed bumps. Keep your speed in check, particularly on long highway drives.
5. Proper Wheel Alignment and Balancing
Unbalanced tyres or poor alignment can lead to uneven wear, increasing the chance of a burst.
How to Prevent Summer Tyre Blowouts?
Summer heat in Pakistan can be brutal, making tyres more vulnerable to blowouts. Here are some summer-specific tips:
- Park in the Shade: Prolonged exposure to direct sunlight can degrade tyre rubber.
- Avoid Driving in Peak Heat Hours: Early morning or late evening drives are safer for your tyres.
- Reduce Tyre Pressure Slightly: Just 1-2 PSI lower than the max limit can help avoid overexpansion due to heat.
- Use Heat-Resistant Tyres: If you live in particularly hot areas like Karachi, Multan, or Lahore, ask for tyres made to withstand higher temperatures.
What to Do If a Tyre Burst Happens
Despite all precautions, a tyre burst can still happen. Here’s how to handle it:
1. Stay Calm and Hold the Steering Firmly
Don’t panic. Keep both hands on the wheel to maintain control.
2. Don’t Slam the Brakes
Braking hard can cause the vehicle to spin out of control. Ease off the accelerator and allow the vehicle to slow down naturally.
3. Signal and Move to Safety
Turn on your hazard lights and carefully steer towards the side of the road.
4. Use Your Spare or Call for Help
If you have the tools and experience, replace the tyre with a spare. If not, call a roadside assistance service or a tow truck.
Final Thoughts
Knowing the reasons behind why a tyre bursts and how to prevent it from happening can save lives. Don’t wait for a close call to take action. Regular tyre maintenance, awareness, and good driving habits go a long way in keeping you safe on the road.
In hot climates like Pakistan, where summer tyre blowouts are more common, being proactive can make all the difference.
Keep your tyres in check, respect your vehicle’s limits, and stay safe out there.
