WASHINGTON-The data in the Rubber Manufacturers Association's recently issued ``Monthly Tire and Tube Report'' for October 1994 showed little impact of the walkouts by United Rubber Workers members then in effect at three Bridgestone/Firestone Inc. tire plants and Pirelli Armstrong Tire Corp.'s two factories. More tires of most types were produced during the month than in October 1993, including a 1.6-percent increase in tractor and implement tires, the category industry observers thought most likely to suffer as a result of the strikes.
Production of radial farm tires, however, did drop 13.5 percent-about 3,000 units-during the month. And October shipments of farm tires to the replacement market slid 10.2 percent to 197,900 units, while those or to original equipment customers slumped 3.7 percent to 73,700 units.
Replacement shipments of all other tire types increased-led by industrial and utility tires, which leapt 31.1 percent to 382,000 units. Light truck shipments jumped 11.5 percent to 2.54 million units, while medium and wide-base truck tires grew 5.4 percent to 1.09 million units. Passenger tires edged up 0.8 percent to 14.9 million units.
