What is a Front Wheel Skid?

Published in Vehicle Dynamics 2 mins read

A front wheel skid, also known as understeer, occurs when the front tires of a vehicle lose traction, causing the car to drift in a direction other than where the driver is steering. Essentially, the car doesn't turn as sharply as intended.

Understanding Understeer

  • Loss of Traction: The front tires don't have enough grip to respond to the steering input.
  • Drifting: The vehicle tends to continue straight ahead, even though the driver is turning the steering wheel.
  • Common Cause: Often caused by entering a turn too fast.

Causes of a Front Wheel Skid

Several factors can contribute to a front wheel skid:

  • Excessive Speed: Entering a corner at a speed that exceeds the tires' ability to grip the road surface.
  • Aggressive Steering: Turning the steering wheel too sharply, overwhelming the front tires.
  • Braking in a Turn: Applying the brakes while turning can shift weight to the front and reduce traction.
  • Road Conditions: Slippery surfaces like ice, snow, or wet roads can significantly reduce tire grip.
  • Poor Tire Condition: Worn or improperly inflated tires reduce traction and increase the risk of skidding.

How to Recover from a Front Wheel Skid

  1. Ease off the Accelerator: Reducing speed allows the weight to shift back to the front tires, improving traction.
  2. Smooth Steering: Gently straighten the steering wheel. Avoid sudden or jerky movements.
  3. Avoid Braking: Braking can worsen the skid. If necessary, use gentle braking after regaining some steering control.
  4. Look Where You Want to Go: Focus your eyes on the path you want the car to follow; this helps with intuitive steering.
  5. Wait for Traction: As the front tires regain grip, gradually steer the car back onto the desired path.

Preventing Front Wheel Skids

  • Reduce Speed: Slow down before entering a turn, especially on unfamiliar roads.
  • Smooth Inputs: Use smooth and gradual steering and acceleration inputs.
  • Maintain Tires: Ensure tires are properly inflated and have sufficient tread depth.
  • Be Aware of Road Conditions: Adjust your driving to account for slippery surfaces.
  • Practice: Familiarize yourself with your vehicle's handling characteristics in a safe environment.
