Over-inflation of tires in commercial vehicles leads to uneven wear and increases the risk of blowouts. When tires are over-inflated, they tend to have a smaller contact patch with the road, which causes the center of the tread to wear more rapidly than the edges. This uneven wear can result in reduced tire lifespan and ultimately affect the safety and handling of the vehicle. Additionally, over-inflation increases the likelihood of tire blowouts, especially when the vehicle encounters road hazards or during sharp maneuvers. The excessive pressure can cause the tire to become rigid, making it less able to absorb shocks from the road. Consequently, even moderate impacts can lead to catastrophic failures. Properly inflated tires are essential for maintaining safe handling, optimizing fuel efficiency, and ensuring maximum tread life, making attention to inflation crucial for commercial vehicle safety.
