SmartWeight Wheel Balancing
®
Eliminating the Operating Costs of Unnecessary Correction Weight & Labor
By Revisiting Wheel Balancing Basics
“This Changes Everything……Except for the Same Smooth Ride”
SLIDE 1
SmartWeight®
• This new wheel balancing method is based on (static) force elimination
and (couple) force reduction. The two forces are treated independently
instead of together as with traditional correction weight sensitivity. A
better job is done eliminating static unbalance and small amounts of
couple force remain yet translate to no vibration and large wheel
weight use reduction.
• Eliminates the operating costs of unnecessary labor & correction
weight.
• Its a simple concept, but
exclusive and patented.

Wheel Balancing
Issues
Average Wheels Balanced in the 70’s and 80’s:
•
•
•
•
14”-15” diameter and 5.0”-7.0” Wide
Almost all were clip-clip weight correction
Average tire size and weight similar
Costs of uncoated lead correction weight very low

Wheel Balancing – Today
Wheels Balanced Today:
•
•
•
•
•
13”- 28” wheel diameters
Wheel widths 5.0”-12.0”
Tire sizes and weight vary dramatically
Flangeless wheel designs are proliferating
Many are open spoke designs and utilize boutique type styling

Wheel Balancing – Today
• Many types of clip weight and
adhesive tape weight styles
continue to proliferate.
• The cost of wheel weights are
dramatically increasing.
• Lead use is becoming restricted
& alternative materials are
significantly more costly.
The average vehicle contains
at least eight wheel weights

Tire Dealers:
• Average 3000 pounds of balance weight/year
• Average $14,000.00 on balance weight/year
• Often use fixed pricing for balance service, regardless
of application
• Often add the price of a balance into the cost of the tire

Wheel Balancing Current Facts
Wheel Balancer Operators:
• Often waste materials by using too much weight.
• Often waste time by encountering repeated check
spins to get the wheel to “Zero”.
• Often risk comebacks due to incorrect
assumptions when balancing.
• Often defeat the balancer design functions and
perform a poor service.

Force vs. Correction Weight Limitations
All wheel balancers have measured imbalance forces of the wheel since
the 1970’s, but have not utilized them efficiently because:
– Limitation #1 - No threshold was placed on the imbalance forces
measured in the tire and wheel. Couple (shimmy) were not isolated
and were treated the same as static balance. This was not
necessary.
– Limitation #2 - Equal importance was placed on the two
imbalance forces. This was also not necessary. Example: Vehicles
tolerate more than a 4:1 ratio of couple to static correction weight on
a 15x6 wheel at clip weight locations.
– Limitation #3 - A single rounding/blinding tolerance was applied to
the correction weight instead of placing limits on the imbalance
forces.

What is SmartWeight™ Balancing?
The first computerized off-car garage balancer
which displays static and couple forces and balances each
force independently of each other.

Some of the New “Corrected” Logic of SmartWeight
1. SmartWeight balancing computes correction weight based on the
absolute static (shake) and absolute couple (shimmy) forces
independently of each other.
2. Separate force limits are based on the amount of imbalance forces
which are known to induce excessive vibration on the vehicle.
Force limit defaults are set below the most sensitive guidelines as
specified by the vehicle manufacturers.

3. SmartWeight two plane dynamic balance is accomplished with a
single weight whenever possible, reducing couple and optimising
reduction in static force.
4. All SmartWeight limits and thresholds are adjustable and may be
programmed from the set up menu, in addition to traditional balance
correction weight rounding.
5. Force limits can be adjusted up or down automatically during the
spin based on the weight (inertia) of the tire/wheel during the
balance spin.

New “Corrected” Logic of SmartWeight
•
SmartWeight puts the appropriate emphasis on each force in the same
manner the vehicle manufacturers calculate thresholds for each force
individually. It computes correction weights based on force reduction
and not merely the displayed correction weight based on dimension
entry.
• A simple way to explain SmartWeight is that “if the force that causes a
vibration is not exceeded, then the correction weight is not needed.”
