Trailer tire blowouts are a common but frustrating issue that can cause significant disruptions, especially when you're on the road transporting equipment or goods. Not only do they lead to delays, but they can also cause damage to the trailer and pose a safety risk. In this article, we will dive deep into the reasons behind tire blowouts, how to prevent them, and what steps you can take when they happen.
What Causes Trailer Tire Blowouts?
Trailer tire blowouts are typically caused by a combination of factors, often linked to improper maintenance, external conditions, and the specific tire's wear and tear. Here are the primary causes:
1. Underinflation
One of the most common reasons for tire blowouts is underinflation. Tires that are not inflated to the manufacturer's recommended pressure generate more heat while on the road. The excess heat can weaken the tire’s structure, increasing the risk of a blowout. Underinflated tires can also reduce the lifespan of the tire, cause uneven wear, and reduce fuel efficiency.
Overloading puts unnecessary stress on the tires, increasing the risk of tire failure. When the trailer is too heavy, the tires are unable to support the load, causing the rubber to stretch and overheat, which leads to blowouts. Even if the tires are correctly inflated, excessive weight can cause the tire walls to deteriorate faster, leading to failure.
Tires naturally degrade over time. The rubber hardens and loses its ability to grip the road, making them more prone to blowouts. Even if a tire appears to have plenty of tread left, older tires can fail unexpectedly due to dry rot or cracking.
Potholes, sharp objects, and road debris can cause immediate damage to tires. A sharp rock or piece of metal on the road can puncture a tire, leading to a sudden blowout. Similarly, hitting a pothole or curb with force can cause a tire to fail.
Tires require regular maintenance, including rotating, balancing, and alignment. Unbalanced tires or improperly aligned axles cause uneven wear and additional stress on the tire, which can lead to a blowout. Additionally, neglecting to replace worn-out tires can cause catastrophic failure when they are pushed beyond their capabilities.
Tire blowouts often don’t happen without warning. Here are some common signs that indicate a tire is on the verge of failure:
1. Vibration or Shaking
If the trailer starts vibrating or shaking more than usual, it might be an indicator that one of the tires is becoming unbalanced or that it has sustained internal damage. These vibrations are often caused by a tire becoming dislodged or a sudden air loss.
2. Low or Uneven Tread
Uneven tread wear can be a sign that the tire is being subjected to excess stress or poor alignment. If you notice that the tread is much lower on one side compared to the other, or if the tire appears flat in the middle, it’s time for a closer inspection.
3. Unusual Heat
Excessive heat buildup is a major factor in blowouts. If a tire feels hot to the touch after driving, it could mean that it’s being overworked. This can happen due to underinflation, overloading, or under- or over-rotation of the tires.
4. Sidewall Bulging
A bulge in the tire’s sidewall is a clear sign of internal damage or a weak spot. These bulges are often caused by an impact, such as hitting a curb or pothole, and they can result in a blowout if not addressed.
Preventing Trailer Tire Blowouts
The best way to handle tire blowouts is to prevent them altogether. Here are some preventive measures:
1. Perform Regular Inspections
Before every long trip, take the time to inspect the trailer’s tires. Look for cracks, bulges, punctures, and uneven tread wear. Ensure that all tires are inflated to the correct pressure, and check the tire’s load capacity to confirm that you're not exceeding the weight limits.
2. Monitor Tire Pressure
Invest in a high-quality tire pressure monitoring system (TPMS). These systems can alert you to any significant changes in tire pressure while you’re on the road, allowing you to take action before a blowout occurs.
3. Rotate Tires Regularly
Just like on your car, rotating trailer tires helps ensure even wear. Uneven wear leads to premature tire failure, and rotating them can help prolong their lifespan.
4. Drive Responsibly
Avoid high speeds, especially when hauling heavy loads. Driving at high speeds increases tire temperatures and the likelihood of blowouts. Sudden stops, sharp turns, and hard accelerations should also be avoided.
What to Do When You Have a Trailer Tire Blowout
Despite your best efforts to maintain and monitor your trailer’s tires, blowouts still happen from time to time. Here’s what to do when one occurs:
1. Stay Calm and Slow Down
If you experience a blowout, stay calm and avoid slamming on the brakes. Rapid deceleration can cause the trailer to become unbalanced. Gently ease off the accelerator and pull over to a safe area as soon as possible.
2. Inspect the Damage
Once you’ve safely stopped, inspect the damaged tire. If it’s safe to do so, use a flashlight or inspection mirror to check for debris that might be stuck in the tire, such as nails, sharp metal, or glass.
3. Replace or Repair the Tire
If you have a spare tire on hand and the tools to change it, replace the blown tire with the spare. If not, you may need to call for roadside assistance or a tow to a repair shop.
4. Learn from the Experience
After the incident, take a moment to review what might have caused the blowout. Did you overinflate or underinflate the tire? Was the load too heavy? Could the road hazards have been avoided? Identifying the root cause can help you prevent similar issues in the future.
Conclusion
Trailer tire blowouts are a common but preventable issue that can disrupt your work and cause costly delays. By maintaining proper tire pressure, monitoring load limits, and performing regular tire maintenance, you can significantly reduce the likelihood of a blowout. In the event of a blowout, staying calm and following the correct procedures can help you manage the situation effectively and minimize damage. Remember, a proactive approach to tire care is always better than dealing with the consequences of a blowout!

The excess heat can weaken the tire’s structure, increasing the risk of a blowout. Underinflated tires can also reduce the lifespan of the tire, cause uneven wear, and reduce fuel efficiency.
- Solution: Regularly check tire pressure with a high-quality gauge. It’s advisable to check tire pressure at least once a week, especially if you're regularly on the road. Ensure the pressure is adjusted based on load and environmental conditions.
Overloading puts unnecessary stress on the tires, increasing the risk of tire failure. When the trailer is too heavy, the tires are unable to support the load, causing the rubber to stretch and overheat, which leads to blowouts. Even if the tires are correctly inflated, excessive weight can cause the tire walls to deteriorate faster, leading to failure.
- Solution: Always ensure that the trailer's load does not exceed the weight limit specified by the manufacturer. Distribute the load evenly to prevent uneven pressure on any single tire.
Tires naturally degrade over time. The rubber hardens and loses its ability to grip the road, making them more prone to blowouts. Even if a tire appears to have plenty of tread left, older tires can fail unexpectedly due to dry rot or cracking.
- Solution: Replace tires that are over six years old, even if they haven’t been used extensively. Regularly inspect tires for visible signs of wear, cracking, or bulging. Keep an eye on tread depth as well to ensure proper road traction.
Potholes, sharp objects, and road debris can cause immediate damage to tires. A sharp rock or piece of metal on the road can puncture a tire, leading to a sudden blowout. Similarly, hitting a pothole or curb with force can cause a tire to fail.
- Solution: Drive cautiously and avoid hitting large potholes or sharp objects on the road. Keep a safe distance from debris, and make sure to inspect tires after every long trip for damage.
Tires require regular maintenance, including rotating, balancing, and alignment. Unbalanced tires or improperly aligned axles cause uneven wear and additional stress on the tire, which can lead to a blowout. Additionally, neglecting to replace worn-out tires can cause catastrophic failure when they are pushed beyond their capabilities.
- Solution: Maintain a consistent tire maintenance schedule. Rotate tires regularly, ensure they are balanced, and check alignment frequently. Regular inspections of the sidewalls and tread area for cuts, bruises, or other damage can prevent further problems.
