These are a yellow crayons . a 'China Marker'. They might work on paper but they are useless on rubber or any other material I have tried.For marking tires use a paint marker instead: Allstar Performance ALL12051 Yellow Paint Marker or Sharpie Oil-Based Paint Marker, Medium Point, Single, Yellow (SAN35554)
