YOKOHAMA TIRE LIMITED WARRANTY W A R R A N T Y Tire Load Never exceed the maximum vehicle load limit listed on the vehicle specification plate. Be aware of the loadcarrying limits molded into the tire's sidewall and do not exceed those limits. Maximum load can only be carried at the maximum cold-inflation pressure indicated on the tire's sidewall. Speed Limits Regardless of the speed capability of your tires, never exceed lawful speeds or speeds dictated by driving conditions. Road Hazards Objects in the road that threaten a tire should be safely avoided. These objects are potholes, glass, metal, rocks, wood debris and the like. If contact with such an object is unavoidable, have your tires thoroughly inspected as soon as possible. Air Pressure Maintenance of proper air pressure is critical to tire life. Air pressure must be checked no less than once a month and before any extended driving. Pressure should be checked when tires are cold (before operation, cool to the touch) using a tire gauge. Maintain air pressure per the vehicle manufacturer's recommendations as noted on the vehicle tire placard or in the Owner's Manual. Do not reduce pressure when a tire is hot, and do not inflate a cold tire to a pressure higher than the limit molded on the tire's sidewall. Remember to also check air pressure in the spare tire. Tread Wear Tires must be replaced when the depth of the tread reaches 2/32 inch (1.6 mm). Yokohama tires are manufactured with tread wear indicators molded into the tire grooves. As tires approach 2/32 inch (1.6 mm) of wear, the tread gauge becomes thinner and more vulnerable to the effects of road hazards. Visual tire inspection therefore becomes more crucial as the tires wear out. 89 Y o u r W a r r a n t i e s i n D e t a i l
