Static balance
Wheel tramp
A. Heavy spot.
B. Add balance weights here.
C. Centre line of spindle.
Static balance is the equal distribution of weight
around the wheel. A statically unbalanced wheel will
cause a bouncing action called wheel tramp. This
condition will eventually cause uneven tyre wear.
Dynamic balance
Wheel shimmy
A. Heavy spot.
B. Add balance weights here.
C. Centre line of spindle.
Dynamic balance is the equal distribution of weight on
each side of the centre line so that when the wheel
spins there is no tendency for side to side movement.
A dynamically unbalanced wheel will cause wheel
shimmy.
