Study Notes

Tire and Brake Performance

  • Regularly checking brakes is essential for optimal performance and longevity.
  • Tire tread depth is crucial for maintaining proper traction.

Understeer and Oversteer

  • Understeer involves front-wheel loss of traction, contrary to the common misconception that it refers to rear-wheel loss.
  • Oversteer refers to a condition where the rear wheels lose traction, leading to a potential loss of control.

Traction Loss

  • Acceleration-induced traction loss specifically affects rear wheels during certain driving conditions.
  • Skidding occurs when a vehicle loses grip during a slide, referred to as sliding traction.

Tire Performance Factors

  • Tire performance is compromised not only by underinflation but also by other factors.
  • Rolling traction pertains to the tires' ability to maintain contact with the road, rather than sliding across it.

Driver-Induced Skids

  • Conditions leading to driver-induced skids can include excessive speed, abrupt clutch engagement on slick surfaces, sudden braking, and rapid changes in steering or speed.
  • Worn braking system components can result in unpredictable wheel lock-up when braking, affecting vehicle control.
