Defect Involved

General Motors has determined that certain 1986 S/T Light Duty model trucks built at Moraine Truck Assembly do not conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) 120, "Tire Selection and Rims for Vehicles Other Than Passenger Cars". The trucks were assembled correctly except that the tire and wheel information on the certification label may be incorrect. Specifically, all of the 5's were changed to 6's (ie. P195/75R14 read P196/76R14 and 15 x 6JJ read 16 x 6JJ). To correct this condition, a new certification label is to be affixed to each affected vehicle. Since a new certification label can be easily installed and to reduce owner inconvenience, new certification labels will be sent diredly to owners of
record. Owners may install the new label or ask a dealer to do the service. Dealer service is to be done at no charge to owners.

VEHICLES INVOLVED Involved are certain 1986 S/T Light Duty model trucks built at Moraine within the following VIN breakpoints:

This recall campaign is to be performed at no charge to owners on all affected vehicles regardless of time, mileage, or ownership. Dealers are to inspect and correct all affected vehicles in new and used vehicle stock prior to their sale. Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle. This bulletin is notice to you that the new motor vehicles involved in this campaign may not comply with the standard identified above. Under Section 108 of the National Traffic and Motor Vehicle Safety Act, it is illegal for a dealer to sell a new

motor vehicle which the dealer knows does not comply with the applicable Federal Motor Vehicle Safety Standard. As a consequence, if you sell any of these motor vehicles without first performing the campaign correction, your dealership may be subject to a civil penalty up to $1,000 for each such sale.
