Tire squeal during turning arises when the lateral force demand on a tire exceeds its maximum friction capacity. This friction limit, governed by factors such as tire compound, road surface, vehicle weight, and turning radius, results in the tire momentarily losing grip and vibrating rapidly against the road. The resulting vibration creates the audible screech.
Understanding the mechanics of tire squeal offers several advantages. It provides direct auditory feedback to the driver regarding cornering limits, potentially preventing loss of control. Monitoring the occurrence and frequency of tire noise can also serve as an early indicator of vehicle maintenance needs, such as suspension component wear or improper tire inflation. Historically, tire noise has also played a role in automotive engineering, providing valuable data for tire compound development and vehicle handling optimization.
