PITTSBURGH—The ACS Rubber Division has settled on co-recipients of the Charles Goodyear Medal, the technical association's highest honor.
Steve Cron and Tim Rhyne, the duo who led the development of Michelin's Tweel non-pneumatic tire technology, will share the medal, the Rubber Division revealed Oct. 5 during its International Elastomer Conference in Pittsburgh. They will receive their medals at the association's 2022 Spring Technical Meeting.
The two collectively spent 70 years at Michelin, with Rhyne working there from 1978 to 2017, when he retired as a senior research fellow. Cron's career at the tire maker began in 1991, and he continues there as a senior principal product research engineer.
Rhyne and Cron in 1997 began informally working on various structural concepts for non-pneumatic tires. Their conversations led to working prototypes that proved the viability of the concepts, and in 2001 they successfully completed a drive from South Carolina to California and back on an early prototype of the non-pneumatic tires.
