Bridgestone will unveil today the production of its first tires at its recently-expanded Graniteville plant.

Company executives and state and community leaders will give an update on the progress of Bridgestone’s $300 million expansion of the passenger car-radial and light truck-radial tire plant, which to date has generated more than 300 jobs, according to the tire manufacturer. The expanded plant is expected to produce more than 12,750 additional tires per day.

Attendees are expected to view the production and signing of the first set of tires, as well as a tire-curing demonstration.

Attendees include plant manager John Stewart, Bridgestone Vice President of Manufacturing Barry Owens, S.C. House Rep. Roland Smith, S.C. Sen. Tom Young, Aiken County Council Chairman Ronnie Young, and Aiken-Edgefield Economic Development Partnership Director Will Williams.

The $300-million dollar expansion is the second phase of a three-part expansion for Bridgestone in Aiken County. The third expansion of the facility is under way.

The expansion, coupled with Bridgestone Americas’ work on its brand new 1.5-million-square-foot off-road radial tire plant in Sage Mill Industrial Park, represents a $1.2 billion investment. It is the single largest capital investment in South Carolina’s history and, in all, is estimated to create more than 850 jobs.

In 2015, off-road radial tires will launch into production.
