Michelin North America today announced it will be increasing its prices by 3 to 8% effective August 1st for tires for commercial vehicle tires as well as those for earthmovers. The announcement follows on the heels of one made by the company on April 23rd that stated Michelin will increase its prices by an average of 3% on passenger and light-truck tires in the U.S. replacement market effective July 5th.

As a group, tire makers have been hit especially hard this year by rising costs for the raw materials used to build tires. Earlier this month Bridgestone/Firestone cited that factor as the reason why it was boosting its prices 5% across the board effective June 1st.
