Tire Blowouts: Causes, Prevention, and What to Do on the Highway

Share on

For professional truck drivers, few situations are as dangerous, and as preventable, as a tire blowout.

A sudden tire failure at highway speeds can lead to loss of control, cargo damage, roadside violations, and serious safety risks. For fleets, it can mean downtime, expensive repairs, increased insurance premiums, and reputational damage.

The good news? Most blowouts don’t happen “out of nowhere.” They’re usually the result of overlooked warning signs.

Let’s break down the causes, prevention strategies, and exactly what drivers should do if it happens.

What Causes Tire Blowouts?

1. Underinflation

The number one cause of commercial truck tire blowouts. Low tire pressure causes excess heat buildup, which weakens the tire’s structure over time.

2. Overloading

Exceeding weight limits puts additional strain on tires, especially steer tires and trailer axles.

3. Road Hazards

Debris, potholes, and sharp objects can damage sidewalls or puncture tires.

4. Worn Tread

Insufficient tread depth reduces traction and increases heat buildup.

5. Improper Maintenance

Failure to perform regular inspections can allow small issues — like slow leaks or uneven wear — to escalate.

How to Prevent a Tire Blowout

Conduct Thorough Pre-Trip Inspections

Drivers should check:

  • Tire pressure
  • Tread depth
  • Visible damage or bulges
  • Foreign objects lodged in the tread
  • Valve stem condition

Monitor Load Weight

Ensure loads comply with provincial weight regulations. Overloaded axles dramatically increase tire stress.

Watch for Vibration or Pulling

Unusual steering vibration or pulling to one side can signal tire imbalance or damage.

Follow Preventative Maintenance Schedules

Fleet maintenance programs should include regular pressure checks, rotations (when applicable), and alignment inspections.

What To Do If a Blowout Happens on the Highway

A blowout is loud, sudden, and alarming — but how you react matters.

1. Stay Calm and Maintain Grip

Keep both hands firmly on the wheel. Do not slam on the brakes.

2. Gradually Reduce Speed

Ease off the accelerator and allow the truck to slow naturally.

3. Maintain Lane Position

Keep the vehicle straight and controlled before attempting to move to the shoulder.

4. Signal and Pull Over Safely

Once speed is reduced and control is stable, carefully move to the shoulder.

5. Activate Hazard Lights and Follow Safety Protocol

Set out reflective warning devices as required by regulation.
