Steven M. Cron is a retired Michelin product research engineer and co-inventor of the Tweel.
[3] Although other airless tire concepts have been studied or attempted in the past, none has achieved the commercial success of the Tweel, which is based on the framework and approach pioneered by Cron and co-inventor Timothy B.
After realizing that cord tension carried via the sidewall would not work with zero inflation pressure, a successful experiment with polyurethane spokes lead to the basic Tweel design.
In 2021, Cron and co-inventor Timothy B. Rhyne were jointly awarded the Charles Goodyear Medal, the highest honor conferred by the American Chemical Society, Rubber Division.
