Chevrolet Sonic Repair Manual: Tire and Wheel Balancing (Road Force Variation (RFV))
- ALL wheel/tire assemblies must have a RFV within spec before being mounted on vehicle.
- RFV is unrelated to tire balance.
- RFV is identifying the stiff portion of the tire and determining if it is within spec.
- If RFV is too high, it will result in a vibration condition.
- Do not attempt to measure RFV on tires that have temporary flat spots. If necessary, drive the vehicle to relieve the flat spots.
- Prior to measuring for RFV, the tires must be inflated to the specification on the label.
- Passenger Cars (including Crossover Vehicles) = 18 lbs.
- Truck Tires: (P) - metric = 24 lbs.
(LT) - metric = 35 lbs.
- It is recommended that RFV measurements are made prior to installation of balance weights. Once adequate road force levels have been achieved, move on to balance the assembly.
Important:
If a wheel/tire assembly is not within the RFV specification after match mounting, the tire must be returned to the tire manufacturer. DO NOT install tire/wheel assembly on a vehicle if it exceeds the RFV specification.

wheel from seizing onto the hub.
