A method of manufacturing a tread band includes providing a mold having one or more protrusions extending outward in a first direction away from a bottom surface of the mold. At least a first one of the protrusions includes a tip feature extending outward in the first direction. Rubber material is introduced into the mold. A first surface of the rubber material opposite the bottom surface covers the tip feature. The rubber material is compressed into the mold. The compressed rubber material covers the tip feature. The mold is released from the rubber material to form a tread band. The tread band has one or more grooves in a second surface opposite the first surface. The one or more grooves correspond to the one or more protrusions in the mold. A first groove corresponding to the first protrusion includes a vent corresponding to the tip feature in the mold.

A process for manufacturing an article made of recovered rubber crumb is provided. According to the process:

a) crumb particles are mixed with particles of a solute;

b) a molded article is produced by molding the mixture from step a) in a closed mold under predetermined temperature and pressure conditions; and

c) the molded article is brought into contact with a solvent so as to dissolve at least one portion of the particles of said solute.

A vehicle comprises a chassis, wheels rotationally mounted to the chassis, each wheel being disposed within a respective wheel well, and a tire mounted to each wheel. A tire sensor disposed within the wheel well senses a tire condition and generates and outputs a tire condition signal indicative of the tire condition. A repair controller receives the tire condition signal from the tire sensor and processes the tire condition signal to determine whether to repair the tire. The repair controller is configured to generate and output a tire repair signal. A 3D printing device disposed in the wheel well and communicatively connected to the repair controller receives the tire repair signal and 3D prints an additive reparation to the tire by drawing a tire repair compound from a supply container within the vehicle and by depositing the tire repair compound on the tire to repair the tire.
