Wheel Balancing
Balancing Wheels Description
There are two types of wheel and tire balance: static and dynamic. Static balance, as shown in figure, is the equal distribution of weight around the
wheel. Wheels that are statically unbalanced cause a bouncing action called tramp. This condition will eventually cause uneven tire wear.
Dynamic balance, as shown in figure, is the equal distribution of weight on each side of the wheel centerline so that when the tire 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: Stones should be removed from the tread in order to avoid operator injury during spin balancing and to obtain good balance.
Each tire 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, usually to
within 1/8 ounce.
