32 IMPORTANT TIRE SAFETY INFORMATION1 clean condition. Bent, chipped or rusted wheels may cause tire damage. The inside of the tire must be free from foreign materials. Have your dealer check the wheels before mounting new tires. Mismatched tires and rims can explode during mounting. Also, mismatched tires and rims can result in dangerous tire failure on the road. If a tire is mounted by error on the wrong-sized rim, do not remount it on the proper rim scrap it. It may be damaged internally (which is not externally visible) by being dangerously stretched and could fail on the highway. Old valves may leak. When new tubeless tires are mounted, have new valves of the correct type installed. Tubeless tires must be mounted only on wheels designed for tubeless tires, i.e., wheels which have safety humps or ledges. Never perform a temporary repair, use an innertube or inject sealant as a permanent substitute for a proper repair. Only qualified persons should repair tires. Be sure that all your valves have suitable valve caps. This will keep valve cores clean and clear and guard against leakage. REPAIRS - WHENEVER POSSIBLE, SEE A TIRE DEALER AT ONCE. Some tire manufacturers do not warrant any inspection or repair process. The repair is entirely the responsibility of the repairer. Punctures in the tread of a passenger tire which do not exceed 1/4 of an inch (6mm) in diameter can usually be repaired by following the Rubber Manufacturer's Association (RMA) Passenger and Light Truck Repair procedures. Contact the manufacturer of your tires for its position and assistance as to the acceptable location for a proper repair and the repair of speed rated tires. Do not use plug repairs. They may cause further damage to the tire. They are not always air tight and the plug may fail. Do not exceed posted speed limits on any repaired tire. Certain tire manufacturers speed ratings are voided if the tire is repaired. Although a tire was properly repaired, internal structural damage resulting from the puncture may have occurred. Sometime later the damage may cause the tire to be removed from service. If the tire has a puncture in the tread which exceeds 1/4 inch (6mm), the tire must be replaced. If any tire has sustained a puncture, have the tire inspected internally by a tire dealer for possible damage that may have occurred. Improper mounting and inflation procedures can cause an explosion of the tire/rim assembly. Only specially trained persons should perform these tasks. Contact your tire store or dealer for assistance. CAUTION -Never, under any circumstance, introduce a flammable substance into a tire. TREAD WEAR INDICATORS (WEAR BARS): Tires contain Tread Wear Indicators (Wear Bars) in the grooves of the tire tread which show up when only 2/32nds of an inch (1.6mm) of tread is remaining. At this stage, your tires must be replaced. Tires worn beyond this stage are dangerous. 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. Unavoidable contact should prompt a thorough tire inspection. You may not always recall hitting an object that can damage or injure your tires. If while driving your vehicle experiences any unusual vibrations, ride disturbance or noise and/or you suspect that possible damage to the tires or vehicle has occurred, DO NOT JAM OR LOCK YOUR BRAKES! Rather reduce your speed and drive with caution until you can safely pull off the road. Stop and inspect the tires. If the tire is underinflated or damaged, deflate, remove the tire and rim assembly and replace it with your spare. If you cannot detect a cause, have the vehicle towed to the nearest vehicle or tire dealer to have the vehicle inspected. WHEEL ALIGNMENT AND BALANCING Wheel alignment and balancing are important for safety and maximum mileage from your tires. Check how your tires are wearing at least once a month. If your tires are wearing unevenly, such as the inside shoulder of the tire wearing faster than the rest of the tread, or if you detect excessive vibration, your vehicle may be out of alignment or balance. These conditions not only shorten the life of your tires, but adversely affect the handling characteristics of your vehicle which could be dangerous. If you detect irregular wear or vibration, have your alignment and balance checked immediately. Tires which have been run underinflated will show more wear on the shoulders than in the center of the tread. (Continued on next page) REPAIRING, MOUNTING AND DEMOUNTING OF TIRES Do not attempt to repair, mount or demount a tire yourself. Tire changing can be dangerous and must be done by professionally trained persons using proper tools and procedures as specified by the Rubber Manufacturers Association (RMA). Follow these mounting recommendations. Your tires should be mounted on wheels of correct size and type and which are in good,
