A computerized alignment system should have
the capacity to recognize several factors that
can affect alignment.
Compensation for Runout
Runout, due to bent or distorted rims, is
common on heavy duty trucks and trailers. The
aligner electronically compensates each sensor
and correctly measures where the axle points.
Identifies and Corrects for Offset
Axle offset on heavy duty trucks and trailers is due,
for example, to mismatched rims. The aligner
allows the technician to measure the distances and
input those measurements, automatically
correcting for offset.

Wheel Balance and Its
Effect on Tire Wear
When aligning the wheels don’t forget
about the importance of proper balance.
Maximizing tire wear requires proper
balance in addition to alignment.
When a wheel and tire assembly is in balance,
gravity will not allow it to rotate from a stopped
position. If the assembly is out of balance,
gravity will force it to rotate when the heavy
portion is in any position but straight down.
When the wheel is put in motion, centrifugal
force acts on the heavy spot, causing the
rotating assembly to pull away from its axis.
The resulting force causes the wheel to “hop.”
This causes vibration and increased tread wear
in the form of “cupping.”
