WASHINGTON-Shipments of medium and wide-base truck tires, as well as tractor and implement tires, to the U.S. replacement market last September lagged the 1993 month, according to recent data from the Rubber Manufacturers Association. The RMA also reported a change in the method by which it estimates replacement passenger tire shipments by non-RMA-member companies. Though these companies account for less than 5 percent of the total shipments in this category, the change resulted in a downward revision of total replacement shipments for the year of 1.74 million units.
Through August, before the revision, replacement passenger tire shipments were running 4.5 percent ahead of 1993 levels. With the revision, the nine-month total-128.5 million units-was 3.2 percent ahead, though the 16 million units shipped in September was 5.4 percent more than the 1993 month.
For the month, shipments of replacement medium and wide-base truck tires slid 3.1 percent to 1.17 million units, though they remained 6.9 percent ahead of 1993 for the nine months.
Replacement shipments of agricultural tires skidded 11.4 percent in September to 190,700 units, and were up just 1.7 percent for the year to date.
