The program calculated the longitudinal and transverse strain using linear elasticity to
determine the effects of wander on measured strain. Figure 6 shows that wheel wander has a greater
effect on transverse strain due to the greater change in transverse strain with offset when compared
to longitudinal strain. For example, if the tire wanders eight inches from the gauge, both strains are
reduced, but the transverse strain is more severely affected although both longitudinal and
transverse strains are identical under the wheel loading. Apparently, the combination of wander
effect (i.e. the steeper slope for transverse strains), as well as the transverse gauges being closer
together, resulted in similar cumulative distribution plots for both transverse and longitudinal
gauges, with the transverse gauges having slightly higher measured differences.
