Usually the area above the racing line on either an oval or road course where rubber scrubbed off tires and other debris come to rest in marble-like particles. ‘‘Getting into the marbles’’ often results in the driver losing control of his car.
Bits of tire debris that lie on the track, usually along the outer edge, and makes it hard for the tires to retain traction when passing theu this debris.
Every circuit has a good racing line. If one is off this line one may encounter marbles, small pieces of debris which are very slippery and may cause a car to go off.
A. See Loose stuff. B. When Earnhardt flipped the car at Daytona, and got back in and finished the race, he proved he has huge Marbles.
(Also referred to as "loose stuff.") Bits of rubber that have been shaved off tires and dirt and gravel blown to the outside of a corner by the wind created by passing vehicles comprise the "marbles" that are often blamed by drivers for causing them to lose control.
Excess rubber buildup above the high groove on the racetrack where a car can lose traction.
Excess of rubber build-up above the groove on the track, the result of normal tire wear thoughout the race.
Loose balls of track surface that have been pulled up at the corners by the grippiness of the cars' tyres. These can then catch out those drivers drifting off the racing line.
When excess rubber builds up above the groove of a tire during a race it’s called marbles.
Excess rubber build-up above the upper groove on the racetrack.
Believe it or not, marbles in racing are loose debris, such as rubber and asphalt, that collect on the track and cause a car to lose traction. Where do they get this stuff, anyway
Excess rubber buildup above the upper groove on the race track.
Loose dirt on the edge of the track. Contains little or no traction and can result into hitting the track's wall.
The accumulated rubber "marbles" that form when the rubber wears off the tires. This accumulation of rubber stays on the track, and if a driver enters the marbles at an excessive speed, his car will lose traction.
Bits of rubber are scrubbed off of racing slicks while cornering. These small balls collect on the outside of the turn, and if a car goes wide (into the marbles, or into "the gray," referring to the lighter appearance of an area covered with marbles) then much adhesion is lost. This often can cause a car to understeer straight into the wall or off the track. With the tire competition between Goodyear and Firestone leading to softer and softer tire compounds, marbles are more of a problem. Organizers use street sweepers to clean these marbles off the track whenever possible.
These are pieces of tire rubber along with dirt and gravel that has been swept out toward the outside wall by the wind created by the speed of the racecars. When cars drive too close to the walls in corners and get into the “marbles,†they lose traction, and then lose control.
