Mounting Tire and
Wheel on Balancer
Wheel Adapters - When balancing large offset
wheels, use this procedure to achieve the best ride
quality available for vehicles with large offset hub
centric wheels. This method assures the wheel is
mounted on the balancer and on the vehicle using
the same location methods.

o’clock at the initial lug nut tightening. Also, the vehicle should be off of the ground at this point. Once all
