“…Tarpinian and Culp [2] observed that the number of coincidences between the tire tread pattern spacing and the rain groove spacing correlated with the driver's subjective rating of groove wander. Their model assumes that the edges of tread elements become interlocked with rain grooves until the increasing lateral stress associated with normal lateral motion of the vehicle caused a sudden release, giving an impulsive effect.…”

A finite element modeling technique is employed in this paper to predict the groove wander of longitudinal tread grooved tires. In generally, groove wander is the lateral force acting on a vehicle's wheel resulting from the combination of rain grooves. If the lateral force of tire is generated by groove wander, unexpected lateral motion of vehicle will happen and it makes drivers uncomfortable. This paper describes the effect of groove wander according to the shape condition of tire tread groove and highway groove using the finite element analysis based on a static loading or a steady-state rolling assumption. The road groove can be located anywhere relative to the longitudinal tread groove. Therefore, the lateral force of the tire is changing depending on the location of the groove road. The numerical results for groove wander prediction of the longitudinal tread grooved tires are compared with the subjective evaluation. It is found that the waveform for the tire with varying grooved road position has a peak-to-peak lateral force in order to estimate the rating of groove wander. The effect of the road groove width and the pitch length on the peak-topeak lateral force of tire is discussed. It is found that the prediction of FEA-based groove wander model using finite element analysis will be useful for the reliability design of the tire tread pattern design.

“…Wander is caused by an imbalance of lateral forces created when tire treads partially overhang a pavement groove [1]. A number of research studies have examined the cause of wander from a theoretical perspective [1][2][3][4][5]. However, little documented work has been performed to develop a suitable measurement system for wander, and wander has proven difficult to measure in the past [6].…”

The objective of the study presented in this paper was to determine the optimal sensor location to assess human discomfort during vehicle groove wander, a phenomenon whereby vehicle occupants experience uncomfortable lateral vibrations when driving over longitudinally grooved (or tined) Portland cement concrete pavement. Field testing was performed over a 4.8 km stretch of interstate highway using a vehicle known to experience vehicle groove wander. Lateral accelerations were measured during wander and nonwander driving at several sensor positions including the seat frame, seat cushion, seat back, and the passenger's head. The most effective sensor location to capture vibrations due to vehicle wander proved to be the passenger's head. The standard methods for evaluating human exposure to vehicle vibrations did not yield a reliable indication of the occurrence of wander or the discomfort it causes.
