Blowouts are common issues commercial truck drivers may encounter on routes. Fortunately, knowing how to identify semi-truck tire problems that may lead to blowouts will prevent you from losing control of your vehicle and keep you out of accidents. Here's why they may occur.

4 Causes of Semi-Truck Tire Blowouts

1. Excess Heat

Driving for extended periods will cause tires to generate excess heat from friction when the rubber rolls over the pavement. This will raise the internal temperature, causing air molecules to expand and leading to overfilling.

Since this makes the rubber less flexible, tires may be more susceptible to blowouts, especially while rolling over potholes. A truck mechanic can check the pressure monthly and remove any excess air.

2. Underinflation

Tires gradually lose air due to payload weights and repeated contact with the road. Additionally, the internal pressure may drop by approximately 1 psi for every 10-degree decrease in outdoor temperature.

When this happens, more of the rubber will make contact with the road, causing the tread to separate and making blowouts more likely. Check the pressure monthly by attaching a calibrated gauge to each valve stem and comparing it to the psi stamped on the sidewall. If necessary, add air at a service shop.

3. Cargo Overloading

Loading cargo in excess of your truck's maximum payload capacity will stress the semi-truck tires. The extra weight forces the rubber to push harder against the pavement, potentially causing tires to explode. Stopping at weigh stations shortly after picking up loads can let you know if you've exceeded the cargo capacity and make weight adjustments to protect the tires.

4. Tire Damage

Damage weakens semi-truck tires and makes them more vulnerable to blowouts. Before embarking upon long routes, inspect the tread for signs of common problems, like punctures or stuck nails. Additionally, take a look at the sidewalls and note any cracks or bulges. If present, a truck mechanic should replace the tires immediately.
