A tire blowout can be one of the most dangerous and startling things to experience on the road—especially at high speeds. Knowing how to prevent a tire blowout and how to react if one happens can keep you safe and potentially save lives.
At Honest Wrenches, we’re all about keeping you on the road safely. Here’s what you need to know.
What Is a Tire Blowout?
A tire blowout is a sudden and explosive loss of air pressure in your tire. It usually happens when the tire is underinflated, worn down, or damaged—and it often occurs while driving at highway speeds, which makes it even more dangerous.
What Causes Tire Blowouts?
Understanding the most common causes of blowouts can help you avoid them:
- Underinflated tires: Too little air causes excessive flexing and heat buildup.
- Overloaded vehicle: Carrying more than your tires can handle increases stress.
- Worn or old tires: Thin tread and brittle rubber are more likely to fail.
- Potholes and road debris: Hitting sharp or hard objects can instantly rupture a tire.
- Extreme heat: Hot roadways and long drives can overheat already weakened tires.
How to Prevent a Tire Blowout
Preventing a blowout starts with regular maintenance and attention to your tires. Here’s your blowout prevention checklist:
Check Tire Pressure Monthly
- Use a quality gauge to ensure your tires are inflated to the manufacturer’s recommended PSI (check the sticker on your driver-side door).
- Don’t forget the spare!
Inspect Tire Tread
- If your tread is worn below 2/32 of an inch, it’s time for a replacement.
- Use the penny test—insert a penny headfirst into the tread. If you can see the top of Lincoln’s head, your tread is too low.
Rotate Your Tires
- Rotating tires every 5,000 to 7,000 miles promotes even wear and extends tire life.
Avoid Overloading
- Check your vehicle’s load capacity (usually in your owner’s manual or inside the driver’s door).
- Don’t pile too much cargo or tow beyond what your tires and suspension can handle.
Replace Old Tires
- Tires over 6 years old (even with good tread) may be dry-rotted or weakened.
- Check the DOT code on the sidewall for the manufacture date.
What to Do During a Tire Blowout
If a blowout happens, your first instinct might be to slam on the brakes or swerve—but try not to. Here’s the safest way to handle it:
1. Stay Calm and Grip the Wheel
Keep both hands firmly on the wheel and try to maintain a straight line.
2. Don’t Slam on the Brakes
Braking hard can cause you to lose control. Instead, let off the gas slowly to gradually reduce speed.
3. Ease Off the Accelerator
Allow the vehicle to slow down naturally. Use light throttle input if needed to maintain control.
4. Steer to Safety
Once the car has slowed, gently steer to the side of the road or shoulder. Activate your hazard lights.
5. Call for Help
If you’re near Des Moines, give Honest Wrenches a call—we can help with roadside service or get you safely to the shop.
After a Blowout: What’s Next?
After a blowout, your rim or suspension might be damaged, and your remaining tires may have been stressed. Be sure to:
- Replace the damaged tire (and maybe all four if they’re the same age)
- Inspect your suspension and alignment
- Check tire pressure in all remaining tires
Honest Wrenches can help with all of that—fast, honest, and reliable service, every time.
