How Does Flat Spotting Occur?
Flat spotting occurs when a vehicle’s tires develop a flat area on the surface, typically caused by prolonged contact with a stationary surface or hard braking. The main components involved in flat spotting are tires and the contact surface.
When a vehicle remains stationary for an extended period, the weight of the vehicle compresses the tire in contact with the ground. This compression can lead to the rubber hardening in that specific area. If the vehicle is not moved for several weeks, the flat spot becomes more pronounced.
Hard braking can also cause flat spotting. When a vehicle brakes suddenly, the tire may not rotate fully, which can lead to localized wear on the contact point.
The sequence of steps leading to flat spotting begins with a lack of motion or sudden braking. Next, the tire’s rubber compounds react to the pressure and heat generated in the contact area. Over time, the surface loses its original shape.
Combining these factors shows that flat spotting occurs due to a combination of weight, immobility, and tire material properties. Understanding this process can help in preventing flat spots through regular movement of the vehicle and practicing smooth braking techniques.
