Which of the following is a valid example of a tire that would require slippage marks?

Explanation:
Slippage marks are used to detect movement of an inner tube relative to the tire. Only tires that use an inner tube can have tube slip, so marks are placed to monitor that relationship. Tubeless tires have no inner tube, so there’s nothing inside that could slip, and slippage marks aren’t applicable. High-pressure by itself or run-flat designs don’t change that fundamental: the key factor is whether a tube is present. Therefore, the valid example is a tire with tubes.
