Lock up
락 업
This occurs when a driver applies the brakes too aggressively, causing the car to continue moving forward while the wheels stop rotating. This results in a "flat spot" on the tire, where one area is severely worn down by the asphalt, leading to significant vibrations and reduced grip during subsequent driving.
🏆 Race Case Study
Lock-Up While Braking Late for an Overtake
When a driver brakes later than usual while attempting an overtake at the end of a straight, the tyres can exceed their grip limit and lock up. A major lock-up can cause the driver to miss the corner and may also create a flat spot that affects the rest of the stint.

Frequently asked questions
Why does smoke appear when a tyre locks up under braking?
When the wheel stops rotating and the tyre slides across the track, intense friction and heat are concentrated on one area of the tyre.
How can a lock-up damage the tyre?
One part of the tyre can wear flat and create a flat spot, which may lead to vibration and reduced grip if severe.
