WASHINGTON—U.S. shipments of replacement tires grew sharply in all categories in May, with one exception—heavy truck tires, the latest Rubber Manufacturer Association figures show. Shipments of heavy truck tires fell 9.7 percent during the month, from a year ago, while those for medium/wide-base truck and light truck rose 12.2 percent and 9.1 percent, respectively.
Passenger tire shipments also improved, but not as dramatically, climbing 4.2 percent.
Tire production, however, was another story. During May, production of passenger tires fell 5.2 percent from a year ago and slid 8.7 percent for heavy truck tires.
As for light truck and medium/wide-base truck tires, production increased during the month but at a slower pace than the increases in aftermarket shipments.
Production of light truck tires rose 6.4 percent in May from the year before, while that for medium/wide-base truck tires increased 3.9 percent.
