Michelin North America is increasing prices on passenger car, light truck and commercial truck replacement tires sold in the United States.

Truck tire and retread prices will increase Dec. 1 on Michelin, BFGoodrich and Michelin Retread Technologies (MRT) brands by an average of 8 percent, according to published reports. Increases will vary by product line.

Yokohama recently announced it's increasing prices on commercial tires by up to 6 percent effective Jan. 1.

Commercial tires went up Nov. 1 at other manufacturers, including Bridgestone/Firestone, Falken, Toyo, Kumho, Hankook and Cooper. In October, Goodyear hiked its truck tire prices. Increases ranged from 6 percent to 8 percent.

Manufacturers are blaming increased costs for energy, transportation and raw materials for the increases.
