 Table 2-2. Tire Specifications

WARNING
Air pressure can affect stability. Temperature changes can affect air pressure. It is important to visually
inspect all tires for proper tire inflation prior to use. Tires should be checked in the operating conditions
experienced by end user on a daily basis. Tire inflation pressures must be checked weekly with a calibrated
gauge. If the measured pressure is less than the specification, re-inflate to the pressure specified. Tires
shall also not be subject to over-inflation above the recommended specification and tolerance range.
