76 GLOSSARY
P, P/SUV, LT
“P Tires” refers to passenger tires, “LT Tires” refers to
light truck tires, and “P/SUV Tires” refers to P-Rated sport
utility vehicle tires.
Patch Balance
Method of balancing that balances weighted rubber
patches applied to the inside of a tire.
PAX
A specifically designed wheel/tire assembly that does not
use the traditional rim lip/bead design. PAX assemblies
require adhesive or patch balancing.
Phase
The position of a vibration cycle relative to another
vibration cycle in the same time reference.
Phasing
The cycle pattern of two or more vibrations that overlap
and combine to increase the overall magnitude.
Pressure Ring
The accessory used to prevent the wing nut from
contacting the wheel when on the balancer shaft.
QuickMatch®
Tire and wheel mounting and balancing method that
matches the loaded runout of the tire in contrast to the
runout of the rim to achieve vibration reduction.
Quick-Thread®
Motor assisted threading of the wing nut for quick
installation and removal.
Radial Force Variation (RFV)
A term describing a measurement of the tire uniformity,
under load, measuring the variation of the load acting
toward the tire center.
Radial Runout
A condition where the tire and wheel assembly is slightly
out of round forcing the spindle to move up and down as
the vehicle rolls along a smooth surface.
Harmonic
A vibration that is identified by the number of occurrences
per revolution. For example, a 1st harmonic vibration has
a once per revolution vibration component.
Hertz
A unit of frequency: one disturbance per second.
Hub Centric
The wheel is centered using the center hole of the wheel.
Inflation Station
A feature on models of the SmartWeight Touch® that
automatically inflates or deflates tires to a predetermined
air pressure.
Lateral Runout
The amount of side-to-side movement as the tire/wheel
assembly rotates.
Load Roller
Feature of balancers that measure SmartWeight®
measurements. The load roller runs perpendicular to the
tire and applies up to 1400 pounds of force to simulate
road conditions.
Lug Centric
The wheel is centered using the lug holes rather than the
wheel center hole.
Magnitude (Amplitude)
The amount of force or the intensity of the vibration.
MatchMaker®
Allows the operator to match up four identical tires on
identical rims, to achieve the optimal combination of
match mounting.
Natural Frequency
The point at which an object will vibrate the easiest.
Order
The number of disturbances per cycle (rotation). For
example, a 1st order vibration occurs once per cycle, and
a 2nd order vibration occurs twice per cycle.
