All of these statements about improper wheel balance are true except . a. dynamic imbalance may cause wheel shimmy b. dynamic imbalance may cause steering pull in either direction c. static imbalance causes wheel tramp d. static imbalance causes rapid wear on suspension components

b. dynamic imbalance may cause steering pull in either direction

Explanation:

              Balancing of a wheel is important in order to avoid vibrations in a vehicle. Balancing of rotating elements are caused by static balancing and dynamic balancing.

             The wrong statement is option (b) because dynamic imbalancing does not cause the steering pull in either of the direction as it occurs due to the vertical vibrations which is caused by the static imbalancing.

Hence the wrong statement is option (b).
