Tire explosions on the motorway can be dangerous and are often caused by several key factors. One primary cause is under-inflation. When tires are under-inflated, more of the tire’s surface area comes into contact with the road, generating excessive heat. This heat can cause the tire to weaken and eventually burst. Another common cause is overloading. Carrying loads beyond a vehicle’s recommended capacity increases stress on the tires, making them more susceptible to failure.
