SAFARI

34 WHEELS & TYRES BalancingWheels : Dynamic balance, as shown in Fig.5, is the equal distribution of weight of each side of the wheel centerline so that when the tyre spins there is no tendency for the assembly to move from side to side. Wheels that are dynamically unbalanced may cause shimmy. General Balance Procedures : Deposits of mud, etc. must be cleaned from inside of rim. Warning : Remove stones from tread, clean the tyre and rim before balancing for safety to achieve better results. Each tyre should be inspected for any damage, then balanced according to equipment manufacturer's recommendation. Off-Vehicle Balancing : Most electronic off-vehicle balancers are more accurate than the on-vehicle spin balancers. They are easy to use and give a dynamic (two plane) balance. Although they do not correct for drum or disc unbalance as does on vehicle spin balancing, this is overcome by their accuracy.
