Bridgestone Corp. is investing $106 million to expand production of radial off-the-road tires at its Hofu plant in Yamaguchi Prefecture, Japan.

The project will raise the company's annual production capacity for small- and medium-sized OTR tires to 16,000 metric tons by year-end 2007, Bridgestone said.

The products, it added, will be exported mainly to Asian and European markets, with some also going to Latin America and to a lesser extent North America.
