Make certain balancer is clean and clear of debris.
(Fig. 1)

Fig. 1

A. Clear heavy objects from top balancer tray.

B. Clear loose weights from under balancer.
Balancer should be sitting on level surface.

5.

Perform “3 spin calibration” located in the advanced
tools menu. Use the calibration weight located on
the right rear of the machine. Follow screen
prompted instructions. (Fig. 2)

Fig. 2

HINT: Consult the Balancer’s operation manual for
additional information.

6.

Perform “Quick calibration check” located in the
tools menu. tools menu. Use the calibration weight
located on the right rear of the machine. Follow
screen prompted instructions. (Fig. 3)

TIRE BALANCE
IMPORTANT: Tires must be “warm” before checking balance. Vehicle must have been
driven at least 5 miles within 20 minutes of balancing tires. Failure to do so may result in
skewed readings due to “cold tire memory” conditions.
10.

Mark the inside sidewall of each tire to note location on vehicle with grease pencil and
remove tire and wheel assemblies from the vehicle.

11.

Mount tire and wheel assembly to balancer using
adapters listed in the quick reference chart at the
end of this document. (Fig. 5)
INCORRECT

12.

Fig. 5

CORRECT

Ensure wheel is fully seated against balancer
spindle flange. (Fig. 6)

Fig. 6

If not fully seated, check for collet contacting the
flange plate opening. Use the Performance wheel
spacer and collet spacers shown in Fig. 7 only to
prevent collet contact with spindle flange.
Use spacers only when needed.

13.

Perform Centering Check.

Fig. 8

 Centering Check PASS. (Fig. 8)
 Proceed to step 14.
 Centering Check FAIL.
 Check wheel hub for debris.
 Verify proper adapters.
Hint: This step is essential to verifying the mounting
of the wheel to the balancer spindle is centered and
correct. If centering check fails, balancer may
provide false readings.
14.

Using the inner dataset arm, set wheel weight
location following the prompts on GSP9700. (Fig. 9)

15.

Check tire balance and road force. (Fig. 10)

Fig. 9

Fig. 10

 Road force variation below Road Force
Limits.
 Proceed to step 16 for balance
adjustment.
 Road force variation above Road Force
Limits.
 Continue to step 17 to adjust road force.
Hint: SET Accessory warranty may request screen
shots of each assemblies balance attached to
warranty claim.
16.

Adjust Road Force
A. Follow Prompts on Hunter GSP9700 to
measure rim run out using dataset arms.
(Fig. 11)
Hint: If outer dataset arm cannot be used due to
wheel design, use only the inner dataset arm.

B. Mark tire side wall and wheel face with grease
pencil as directed by Hunter GSP9700. (Fig. 12)
Hint: If balancer indicates no road force
improvement can be made by phase matching, the
source of high road force maybe tension in tire
sidewall or bead. Proceed to with dismounting and
remounting tire to wheel to ensure proper assembly
and relieve tension before condemning tire.

Fig. 12

C. Dismount tire using appropriate equipment and procedures.
D. Apply lube to both tire beads. Ensure lube
covers all areas the bead will contact the wheel
during mounting and entire circumference of
bead. (Fig. 13)

Fig. 13

E. Apply lube to wheel in areas shown in Fig. 14.
Bead safety humps and drop center portions
should be lubed thoroughly.
Hint: Lube is essential in allowing a tire to properly
seat on the bead during tire inflation. The
effectiveness of lube will decrease over time.
Advise the customer to avoid hard acceleration or
sudden stops for 500mi after service.

Fig. 14

F. Mount tire using appropriate equipment.
G. Align grease pencil markings on tire and wheel. Ensure tire is centered on wheel.
H. Tire inflation:
 Inflate tire slowly, beads should move into position against the outer edge of
the wheel with low air pressure, less than 15psi. Loud pops or additional
pressure required may indicate lack of lubrication and bead tension.


After beads are seated, inflate to maximum bead seat pressure as indicated
on tire sidewall. Never exceed maximum bead seat pressure.



Allow the tires to rest for 3-5 minutes.



Completely deflate tire to relieve pressure on bead.



Inflate to operating pressure.

Hint: Some tire machines such as the Hunter Revolution utilize a bead massage
function. Bead massage function is recommended if the machine is applicable. Consult
tire machine operation manual for details.
I.

Return to Step 11 to mount to balancer and recheck balance and Road Force.

NOTE: If the same tire fails road force after performing this procedure (step 15) twice,
Record road force on repair order and on tire with grease pencil. See Accessory Tire
Warranty Policies and Procedures listed on SET Dealer Daily.

NOTE: Wheel machining / finish may not always be true to rim bead surface. This could
cause an illusion of wheel run-out concerns. If rim run-out is suspected dismount the tire
and measure bare rim run-out with the GSP9700 to verify condition.

17.

Adjust Tire Balance
A. Remove all weight from wheel using a nongouging tool. Clean tape residue left from
adhesive tape. (Fig. 15)

B. Recheck balance to determine exact weight
needed. (Fig. 16)

NOTE: Southeast Toyota Vehicle Processing
centers utilizes 3M tape weight systems (Fig. 17)
which can be cut to precise lengths in 1 gram
incriments. See www.3m.com for details.
This procedure has been written using this weight
system. While Southeast Toyota recommends the
use of this product due to ease of use and accuracy
of weight, dealer technicians may alter process
using weight available in shop.

Fig. 17

C. Cut the exact amount of weight as indicated by
balancer. (Fig. 18)
o

When less than 42g (1.5oz) of weight is
needed, use 4x23mm weight 3M PN61405

o

When greater than 42g (1.5oz) of weight is
needed, use 6x29mm weight 3M PN99473
Fig. 18

D. Apply Weight to wheel in locations indicated by
Hunter GSP9700. (Fig. 19)

Fig. 19

A. Perform check spin to verify balance correct.
(Fig. 20)
Repeat this step 14 as needed until optimal
balance is achieved.

18.

Follow Service Procedures to remount wheels and tires to vehicle in the original
locations.
Hint: Placing a questionable tire in the rear ensures a repeat repair after the tire rotation.

19.

Test drive vehicle in conditions previously identified in step 2 to confirm vibration levels
observed in step 3 are no longer present.
If vibration concern is unchanged, create a Technical Assistance on TIS. Then Call SET
Accessory Hotline (888)851-2722, press 3 for technical assistance.

Hint: Some improvements to steering wheel flutter
or shimmy at highway speeds have been noticed
with the following considerations within Toyota’s
alignment specifications (Fig. 21):


Set Caster to 3.3-3.5 degrees.



Toe should be set positive +0.10–0.15
degrees. (+0.2-0.3 degrees total toe)

Cross caster and camber should never exceed 0.5
degrees.
