Dear GMC Truck Owner:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
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 fire and wheel information on the certification label may be incorrect. Specifically, all the 5's were changed to 6's (i.e. P195/75R14 read P196/76R14 and 15 x 6JJ read 16 x 6JJ).
To correct this noncompliance, a new certification label should be installed on the affected vehicles. We have enclosed a new certification label. For your convenience, you may install it yourself. Just follow the instructions on the reverse side of this letter.
If you prefer, you may arrange a service date with your GMC Dealer. They will be pleased to install the new label for you at no charge.
If you decide not to install the new label yourself, your GMC Dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not remedy this condition on that date or within five days, we recommend you contact the nearest GMC Zone Office. The Zone Office will assist you and the dealer in getting your vehicle corrected. The locations and telephone numbers of the Zone Offices are listed in your Owners Manual.
After contacting your dealer and the Zone Office, if you are still not satisfied that we have done our best to remedy this condition without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590, or call 800-424-9393 (Washington, D. C. residents use 426-0123).
If you install the new certification label or if you have sold or traded your vehicle, please complete the enclosed postage paid owner reply card and mail it to us. This will assist us in assuring that all affected vehicles have been corrected.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our products.
