Marbles
Small pieces of rubber that accumulate off the racing line, reducing grip for cars that run over them.
What is Marbles?
Marbles are small pieces of rubber that are shed from Formula 1 tyres during a race and accumulate off the racing line. As tyres wear, small balls of rubber are deposited on the track surface. These marbles are extremely slippery — a car that runs over them loses grip significantly. Marbles accumulate on the outside of corners and in areas that are not regularly swept by passing cars. Drivers who run off the racing line (e.g., when defending against an overtake) risk running over marbles and losing control. The accumulation of marbles is more severe with softer tyre compounds and in hot conditions.
History in Formula 1
Marbles have been part of F1 since the beginning. The problem became more significant with the introduction of high-degradation Pirelli tyres in 2011, which shed more rubber. Marbles are a significant factor in race strategy — drivers who run off the racing line risk losing time or control.
