How To Prevent Semi-Trailer Tire Blowouts?

Semi-trailer tire maintenance is undoubtedly one of the most critical safety components in trailer maintenance. According to data from the Federal Automobile Data Transportation Security Administration, truck accidents caused by tire problems account for 6% of all.

Among these tire problems, the most common tire problem faced by truck drivers is truck tire blowouts. A semi tire blowout will cause the driver to lose control of the trailer or even rollover. If the tire debris is accidentally expelled, it will cause danger to other vehicles on the road. In the event of an 18-wheeler tire blowout, the truck may jackknife or become unmanageable.

What factors can cause blowouts?

There are usually two reasons for blowouts: do not inspect the tire regularly, and do not maintenance and replacement tires when necessary. If the driver or company does not find worn or defective tires, these tires will explode or quickly lose air pressure due to sudden pressure.

The causes of tire wear usually include:

  • Under-inflated tires: Over time, tires may lose air naturally, so tire pressure should be inspected regularly. When you drive past potholes or sharp objects, the tires may suddenly leak.
  • Tire over-inflation: From mid-May to early October, it will be the tire blowout season. Because the outdoor temperature is the hottest at this time, the driver drives a heavier trailer farther and faster. So, in this season, both the driver and the transportation company should strengthen the inspection of tires.
  • Cargo overload: If the tires are already under extreme pressure, adding extra weight that exceeds the capacity will cause any tires to blowout.
  • Wear and tear of the tire: The semi-trailer tires need to bear a lot of weight even when it is not in use. Therefore, wear is inevitable.
  • Tire mismatch: When the size of the tire is not suitable for the semi-trailer, there is also the risk of a tire blowout. Therefore, when replacing tires, you should be replaced according to the factory size.
