1996 Mercury Sable Owner's Manual - Page 317

RWARNING Over- or under-inflated tires can affect vehicle handling and can fail suddenly, possibly resulting in loss of vehicle control. Consistent high-speed driving RWARNING Ford Motor Company recommends obeying the posted speed limits. Driving too fast under certain conditions is dangerous and could cause loss of vehicle control or breakdown of certain vehicle components resulting in personal injury. In the event of continuous operation at high speed, the cold air pressure in all tires must be increased by 4 p.s.i. (28 kpa) when compared to the inflation pressure shown on the tire decal posted in the glove compartment. Under no circumstances should you exceed maximum tire inflation pressure which is molded on the tire outer side wall. Your vehicle has been equipped with proper speed rated tires to meet its speed capabilities. For further details, consult your Tire Warranty Booklet provided with the vehicle in the glove compartment. 290
