A change in force exerted on the axle by the tire/wheel assembly while rotating under
load. Units of measurement are in pounds, Newton's, etc.
The ability to locate varying positions of the tire/wheel assemblies and hold the position in
place while correctional weights or OE-Matching marks are applied.
SmartWeight measures the forces placed on a wheel and balances in an effort to
reduce those forces, thus saving weight, time, and money.
A component causing another object to vibrate, such as a tire/wheel assembly.
®
A feature that locks the spindle in place by depressing the foot pedal.
A procedure that balances the wheel assembly using only a single weight plane.
An abbreviation for top dead center. Also referred to as 12 o'clock.
The vibration occurs when accelerating, decelerating, or applying the throttle.
Data measurements taken by the load roller (measured in lbs. or kg) or Dataset® Arms
(measured in inches or millimeters) representing the actual runout measured. The T.I.R.
data represents the difference in value between the highest and lowest value measured.
The object(s) that transfer the frequency.
A shaking or trembling, which may be heard or felt.
WeightSaver™ is the percentage of maximum shimmy allowed. The larger the
percentage, the greater the weight savings.
Dimension measured on the inside of the rim at the bead seats.
The measured distance between the mounting face of the wheel and the centerline of the
rim.
Dimension measured on the inside of the rim between the bead seats.
