Lateral Runout
The amount of side-to-side movement as the tire/wheel assembly rotates.
Load Roller
Feature of balancers that measure Road Force® 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.
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.
