<FONT face="Comic Sans MS">I've used this system for all of my new tires purchaser and swear by it. Exactly like when the car was new..... Zero vibration at any speed.
To elaborate a bit, from the Hunter Wheel Balancing web site:
What Causes Excessive Wheel Vibration?
Wheels Out of Balance
Static wheel balance measures only "up and down."
Static wheel balancing uses a single weight plane and only addresses "up-and-down" imbalance. This is simply not adequate for today's vibration sensitive vehicles.
Dynamic wheel balancing uses two weight planes. This eliminates "up-and-down" and "side-to-side" imbalance. Dynamic, two plane wheel balance should always be requested, even on custom wheels when hidden weights are required.
Dynamic wheel balance also measures from "side to side."
Wheel Force Variation
An out of round tire (runout) causes wheel vibration.
A stiff spot hitting the pavement causes vibration.
A perfectly balanced tire can still vibrate due to Force Variation.
Wheel Force Variation is most frequently due to wheel runout or uneven tread or sidewall stiffness in the tire. Runout is when a tire or rim is out of round when rolling; frequent causes are a bent rim or uneven tire wear.
Uneven tread or sidewall stiffness can be found in new or worn tires. Tires by design are never uniformly flexible throughout nor are they perfectly round. And no two tires are exactly alike in these characteristics.
How Wheel Force Variation is Corrected
OEM Match Mounting matches a high point or stiff spot on a tire with the low spot on the rim, for maximum roundness.
1. Match mounting a tire and rim by matching the high point or stiff spot in the tire with the lowest spot in the rim, can make the wheel "round when rolling."
2. In some cases a wheel is so out of round it should be replaced.
3. In some cases a tire with excessive Force Variation is defective.
Tire Pressure and Wheel Alignment
Improper tire pressure and/or misalignment causes irregular tire wear which creates and amplifies imbalance, resulting in wheel vibration. Alignment can be adjusted and wheels serviced to reduce or stop the vibration. Ask your technician.
Steering and Suspension Components
Steering and suspension components need periodic inspection. They can eventually wear out resulting in wheel vibration. Excessive wheel vibration from other causes can also shorten steering and suspension component life.
Other Hidden Causes of Wheel Vibration
Wheel to axle mounting error
Brake component wear or failure
Drive train or engine component wear or failure
