Michelin North America plans to dramatically cut back its popular Bib Bucks contingency program but also plans to lower retail prices on racing tires, insiders say. According to sources close to the company, Michelin plans to offer Bib Bucks to racers at AMA Pro, Formula USA and WERA National races only, paying in all classes. Bib Bucks will no longer be awarded at regional events, if the plan proceeds as it currently exists, but tires sold at regional events will cost less. Michelin’s Randy Richardson declined to comment on the reports and referred Roadracing World to Michelin spokesman Steve White, who had not responded to a voice mail message at post time.
