Work has already begun on the expansion, Yokohama said, and production there should start by November.
The project will increase Yokohama’s monthly OTR tire production capacity to 1,620 tons by 2009, up from 1,100 tons today.
Demand outside Japan accounts for about 80% of Yokohama’s OTR business.
The increased production will supply 25-, 33-, and 35-inch radial tires, used primarily on construction and mining equipment.
