DIRECTIONALLY PATTERNED TIRES INFORMATION/USAGE for Chevrolet Chevy MD FWD Control Chassis 1986

THE PURPOSE OF THIS BULLETIN IS TO CLARIFY SOME MISCONCEPTIONS CONCERNING THE MOUNTING OF DIRECTIONALLY PATTERNED TIRES. ALL TIRES USED BY GMC ARE NON-DIRECTIONAL. THE RELATIVE POSITION OF DIRECTIONALLY PATTERNED TREAD DESIGNS WILL GIVE EQUIVALENT PERFORMANCES WITH RESPECT TO HANDLING, TRACTION AND WEAR, REGARDLESS OF TREAD DIRECTION AND MIXTURE ON A GIVEN AXLE OR VEHICLE. THEREFORE, IF THE TIRES ON A VEHICLE DO NOT HAVE THE TREAD DESIGN ALL GOING IN THE SAME DIRECTION, DO NOT REMOUNT THE TIRES FOR IMPROVED PERFORMANCE. GMC/CHEV DISCLAIMER

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
