A folding wheel chock has a stop ramp having a front face shaped to interface with a vehicle wheel, extending from a first support base to a first vertex, and a support wall extending from a second support base to a second vertex. The stop ramp and the support wall are hinged by a pivot pin at the respective first and second vertexes to rotate between an in-use or working configuration and a non-use or resting configuration. The folding wheel chock has a tip acting as a portion of the first interface with the vehicle wheel, the tip associated with the stop ramp and movable from an extracted or working configuration, in which it protrudes towards an associable wheel as an extension of the stop ramp, to a retracted or resting configuration in which it is arranged at least partially folded or aligned on the stop ramp and/or support wall.
