HARSH RIDE Z-51 SUSPENSION LOWER COLD TIRE PRESSURE

RIDE HARSHNESS ASSOCIATED WITH THE Z-51 SUSPENSION OPTION MAY BE A SOURCE OF CONCERN TO SOME CUSTOMERS. RIDE HARSHNESS CAN BE SIGNIFICANTLY CHANGED BY REDUCING THE COLD TIRE INFLATION PRESSURE FROM 35 PSI TO 26 PSI. OPERATION AT A TIRE PRESSURE OF 26 PSI COULD RESULT IN A SLIGHT DECREASE IN FUEL ECONOMY AND A SLIGHT INCREASE IN TIRE WEAR DEPENDENT ON DRIVING HABITS.

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.
