A series of highway and laboratory experiments were performed to assess the performance of a vibration-reducing tire additive product. The laboratory dynamometer tests showed that the additive, EQUAL Automotive Formula, reduced the vertical (Z-direction) vibration magnitude at the fundamental frequency (one per tire revolution). The average reduction compared to dual plane balanced wheel assemblies was 29% in on-vehicle acceleration dynamometer testing, and 55% in fixed axle dynamometer testing. Highway experiments showed that both tire-induced and periodic road-induced vibrations were consistently reduced. Videos created of the particles moving dynamically within a rotating tire aided in understanding the mechanism by which tire vibration is reduced. Based on the experimental and video observations, we present an explanation summarizing the vibration reduction behavior as three simultaneous mechanisms.
