A tire tread depth indicator molded into a tire tread surface provides a visually measurable indication of wear of tire tread depth for a vehicle tire. The tread depth indicator has a cog shape with a plurality of depth indicator teeth distributed equally around the cog shape and each of the depth indicator teeth has a depth corresponding to a tread depth measurement. The graduated depth of the tire tread depth indicator sequentially wears down at a rate that corresponds to the wear of the tire tread. A molding element and a method of using the molding element according to the invention forms a tire tread depth indicator having a cog shape with plurality of graduated height indicator teeth and segments distributed around the cog shape molded into a tire tread surface and provides an accurate visual measurement of tire tread depth over time of use.
