What is a common cause of tire blowouts in commercial vehicles?

Under-inflation or overloading is a significant cause of tire blowouts in commercial vehicles. Tires are designed to operate under specific pressure levels, and when they are under-inflated, the tire may overheat due to excess flexing. This excessive heat can lead to a breakdown of the tire's materials, ultimately leading to a blowout. Additionally, if a vehicle is overloaded, the tires are subjected to more weight than they are designed to carry, causing increased stress and heat buildup. This combination of improper tire inflation and an excessive load can quickly lead to premature tire failure.

While improper wheel alignment, excessive speed, and poor road conditions can also contribute to tire issues, their impact is not as direct as that of under-inflation or overloading in causing blowouts. Properly maintaining tire pressure and adhering to load limits are critical for ensuring the safety and operational efficiency of commercial vehicles.
