What type of scuff mark is created when a tire is undergoing acceleration?

When a tire is undergoing acceleration, it creates a specific pattern of scuff marks known as an accelerating scuff. This type of scuff mark indicates that the tire was spinning faster and gaining traction against the road surface as the vehicle moved forward.

During acceleration, the forces acting on the tire cause it to push against the road, resulting in the rubber of the tire being worn in a distinctive pattern. This pattern typically appears wider and has a more pronounced marking where the tire's contact patch experiences increased friction and heat due to the acceleration.

Recognizing the characteristics of an accelerating scuff is crucial for accident reconstruction and understanding the dynamics involved in a collision or skid scenario. It aids investigators in determining the behavior of the vehicle just before an incident occurred, contributing to accurate assessments of speed and loss of control.
