Tokyo (December 6, 2010) – Bridgestone Corporation today announced that effective March 1, 2011 it will raise the prices of truck and bus tires sold in the Japan replacement market an average of 7.0%. This applies to both summer and winter tires.
The price of natural rubber has continued to increase at an unprecedented rate. In addition, the price of petrochemical-based materials such as synthetic rubber and carbon black remain at high levels.
Bridgestone has implemented internal measures to mitigate rising raw material prices through increased productivity and enhanced manufacturing efficiencies. However, due to the amount of natural rubber necessary in the production of truck and bus tires, raw material price increases have risen to a level that can not be overcome entirely through internal measures.
