Form by compressed air pressure. Pressure Forming, an enhanced version of Vacuum Forming, is another of the thermoforming methods that is widely used. It forms product by using compressed air to stretch the sheet to be formed in the mold after heating and softening it.
These range from simple sheet bending, using a folding machine or jig, to more complex processes, such as vacuum forming and pressure forming, which use negative pressure (vacuum) and/or positive pressure (compressed air). When higher pressures and more traditional compression molding ...
and this one explains that the tread is formed during the final curing stage, by inflating the hot tire “blank” inside a mould: https://auto.howstuffworks.com/how-tires-are-made2.htm
“Green tires go into a mold, where they're inflated. Inflating the tire causes it to press against the mold. As a result, the mold imprints the tread pattern and tire information on the tire. While in the mold, the tire is heated to over 300 degrees Fahrenheit (149 degrees Celsius) to cure the rubber and bond the components. It stays over that temperature for about 15 minutes for passenger car tires -- bigger tires, like truck tires, may cure for an entire day. The heating process is known as vulcanizing the tire.”
