Budd–Michelin rubber-tired rail cars which featured innovative and distinctive pneumatic tires. The company claimed that its application of tires on its rail cars afforded both a substantially more cushioned ride and increased the cars' traction by 35%. The design of Michelin's tired wheels included an aluminum safety ring and a flange that were only used in the event of a puncture or other type of tire failure; during normal operation, only the rubber tire made contact with the rail. Inspired by Michelin's success, the Budd Company set its sights on marrying the new rubber rail tires with its shot-welded, stainless-steel carbodies; it had developed
Waste tires other tires. To convert the waste tire into a valuable product, it must first be reduced in size and then recycled. The recycling process begins first by shredding tires into small manageable chips, which are then cooled to cryogenic temperatures, causing the pieces to become brittle. These brittle pieces are then pulverized into a material that must be screened to remove large chunks of rubber or polymer. Finally, the remaining fibre and magnetic material are separated from the pulverized material using a magnetic separator and a vibrational separator. This form of recycling is environmentally friendly, and allows a valuable resource
