For runflat operations, refer to table 2-4. .WARNING. • Do not exceed 30 mph (48 kph) during any runflat operation. Do not exceed 20 mph (32 kph) with both rear tires flat. Loss of vehicle control may occur, causing damage to equipment and injury or death to personnel. • Speeds indicated in table 2-4 are maximum and must be reduced when traveling on secondary roads, cross-country, or in traffic. Failure to reduce speeds could cause loss of control of vehicle, causing damage to equipment and injury or death to personnel. • When driving vehicle, existing conditions are constantly changing. Never drive at a speed greater than is reasonable and prudent for these conditions. Loss of vehicle control may occur, causing damage to equipment and injury or death to personnel. CAUTION • A wheel that has been run flat must be replaced and inspected by unit maintenance as soon as possible before reuse, or damage to equipment may result. • Runflat operation may cause the tread to separate from the tire and/or wheel. If abnormal handling is experienced, or noise such as flapping or pounding around the wheel well occurs, the tread needs to be cut away from the wheel before continuing operation. Failure to do so could result in damage to the vehicle. NOTE Runflat travel distance will improve with rubber runflat. If additional travel is required, tire tread may be cut away from tire.
