Wheel Balancing: Inspection

WARNING: This page is about a different car, the 2004 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.

Proper wheel balance may be lost if the tire is repaired or if it wears. Check the tire for dynamic balance, and repair as necessary.
To check for dynamic balance, use a wheel balancer. Drive in the balance weight on both the top and rear sides of rim.
Some types of balancer can cause damage to the wheel. Use an appropriate balancer when adjusting the wheel balance.
Use genuine balance weights.
NOTE:
- 55 g (1.94 oz) weight used with the aluminum wheel is not available.
- Balance weights are available for use with any of 15 to 17-inch wheels.
