[n] - a children`s game played with little balls made of a hard substance (as glass)
Small chunks of discarded tyre rubber (from blistering and graining) that build up at the side of the track, off the racing line. Drivers try to “stay out of the marbles,” as the track surface in these areas can be very slippery.
noun a children`s game played with little balls made of a hard substance (as glass)
The small pieces of tyre rubber that accumulate at the side of the track off the racing line. Typically these are very slippery when driven on.
Excess rubber build-up above the groove on the track, the result of normal tire wear throughout the race.
Rocks and debris that collect off the racing line. If a driver enters the marbles at an excessive speed, his car will lose grip and drive perilously into awaiting hazards as if a person walked across a bed of marbles.
