you do not need to remeasure the wheel or reset

the wheel measurements. Mount the tire, remove

any weights, lower the hood, and press START.

Alloy Balancing

Specialty  wheels,  balanced  with  adhesive  backed

weights  hidden  on  the  inner  surface  of  the  wheel,

should  be  balanced  in  the  ALLOY  mode.  When  the

ALLOY mode is selected, the computer automatically

calculates the outer weight position as the middle of

the rim width. The inner weight position is under the

inner  flange  of  the  wheel  (Figure  10).  All  alloy  wheel

dimensions  are  measured  and  entered  into  the

balancer  in  the  same  manner  as  described  in  the

Entering Wheel Measurements section.

Weights  must  be  attached
securely  to  wheel  surfaces
cleaned according to weight

manufacturer’s recommendation. Failure to do so
may  cause  weight  to  come  loose  during  a  spin,
resulting in personal injury.

Two Adhesive Weights, Outside Weight Visible

1. Mount wheel and remove weights.

2. Press  Mode  key  until  the  ALLOY  LED  is

illuminated.

3. Enter  wheel  offset,  diameter,  and  rim  width

measurements.

4. Lower  the  hood  and  press  START.  Wait  for

readings to appear and wheel to stop.

5. Raise the hood and rotate wheel until left weight

position lights blink.

Figure 10 - Two Adhesive Weights, Right Weight Visible

6. Attach  the  specified  weight  to  the  left  plane  of

the wheel.

7. Rotate wheel until the right weight position lights

blink.

8. Attach  the  specified  weight  to  the  right  plane  of

the wheel.

9. Lower  hood,  press  start,  and  respin  the  wheel.

Repeat Steps 5 through 8 until readings are 0.00.

NOTE: It is recommended that adhesive weights are

covered  with  aluminum  foil  or  duct  tape  to  keep  the

weight clean and securely attached to the wheel.

IMPORTANT: After placing the balanced wheel on the

vehicle,  check  for  adequate  clearance  between  the

weight and the brake caliper.

Static Balancing

Static  balanced  wheels  may  wobble  if  the  imbalance

mass is large enough and off the centerline of the rim

width. Wobble caused by an off center imbalance can

be corrected only by dynamic balancing of the wheel.

When  the  STATIC  mode  is  selected,  the  computer

automatically calculates the middle of the rim width as

the proper weight position (Figure 11).

All wheel dimensions are measured and entered into

the balancer in the same manner as described in the

Entering Wheel Measurements section.

1. Press  Mode  key  until  the  STATIC  LED  is

illuminated.

2. Lower  hood  and  press  START.  Wait  for  the

reading  to  appear  and  the  wheel  to  stop.  The

weight displayed is the weight required to balance

the wheel (within 0.25-ounce).

3. Raise  the  hood  and  rotate  the  wheel  until  the

weight position lights blink.

4. Attach  the  specified  weight  to  the  center  of  the

wheel.

Figure 11 - Static Balance Weight Position

NOTE: It is recommended that adhesive weights are

covered  with  aluminum  foil  or  duct  tape  to  keep  the

weight clean and securely attached to the wheel.

IMPORTANT: After placing the balanced wheel on the

vehicle,  check  for  adequate  clearance  between  the

weight and the brake caliper.

NOTE:  If  using  static  balancing  mode  with  clip-on

weights,  add  1.5-inches  to  the  rim  diameter  to

compensate for weight placement.
