Summary
This is a Technical Journal: we find with automobiles. Radial force variation ( RFV ) is a condition where excessive run out will create the same symptom as an unbalanced tire. Tire balancing should be checked and corrected as needed but is not always the solution. Road Force balancing detects assembly run out measured under load simulating real world driving conditions and will provide a solution to match mount the tire and rim to minimize loaded run out.

DESCRIPTION:
Tires have changed over the years and are one of the more common problems that we find with
automobiles. Radial force variation (RFV) is a condition where excessive run out will create the same
symptom as an unbalanced tire
Today tires are much lower profile, the sidewall is much stiffer. This means that minor flaws in the tire
and rim can be amplified and transmitted into the car causing excessive vibrations.
Tire balancing should be checked and corrected as needed but is not always the solution.
Road Force balancing detects assembly run out measured under load simulating real world driving
conditions and will provide a solution to match mount the tire and rim to minimize loaded run out.
Note: Rims and tires are not going to be perfect and rim, tire matching may be necessary.
Road Force Balancing should also be done when mounting new tires.
SERVICE:
If customer complaints of a vibration at highway speeds perform Road Force Balancing/ Matching.
Please refer to ST-227 (Attached)
Max allowable road force measurement 90N (20 Lbs.)
VEHICLE REPORT:
Yes, please submit a vehicle report with the Road Force Measurements attached if the service in this TJ
did not bring road force to allowable readings. Use concern area “Vehicle Report “ and sub concern area
“ Support Needed “. Use function group 7721. Report title should say (Road Force).
Operation 07726-6 can be claimed up to a maximum of 2.5 hours.
If less than 2.5 hours is needed, the claim shall not exceed the actual punch time flagged.
Usage of operation 07726-6 is subject to the general operation time policy, including a separate punch
time for each repair.

“Right first time in Time”
As Volvo Sales and Service volumes increase and our vehicles increase in value and complexity, it
is important that our service facilities keep pace with customer expectations. In order to meet this
challenge it is essential that our Retail Partners have the proper Volvo recommended shop equipment
needed to properly diagnose and repair vehicles the first time every time.
This statement comes into focus and currently relevant as it pertains to tire and wheel vibration
concerns. Many of the customer concerns relating to tire vibration could be corrected with the use of a
high quality Road Force Tire and wheel balancing machine.
