Your car shakes at highway speed and nobody can figure out why. You have had the tires balanced twice. You have had an alignment. You have even replaced tires. It still shakes. The answer is probably road force balancing — and most shops do not have the equipment to do it.
What Makes Road Force Different
Standard balancing spins your wheel in the air and adds weights until it balances. Road Force balancing does the same thing PLUS presses a large roller against the spinning tire to simulate road contact. This detects force variation — stiff spots in the tire that cause vibration even when the wheel is perfectly balanced.
Do You Need It?
Yes, if: Your vehicle vibrates at highway speed despite standard balancing. You have new tires that still vibrate. You have large tires (33s, 35s, 37s) where force variation is amplified. You are picky about ride quality.
Maybe not if: Your vehicle rides smooth after standard balancing. You have small, lightweight tires.
Cost
Road Force balancing is $20-$40 per tire ($80-$160 for all 4) versus $10-$15 per tire for standard. At AFW, we are one of only 2 shops in the KC metro with a Hunter Road Force Elite.
