ABSTRACT

To realize a substantially eco-friendly tire that simultaneously offers appreciable drivability and traction performance, the authors have developed and proposed a large and narrow tire technology called “ologic” considering size and inflation pressure effects as one of the next-generation tire technologies.

In this study, exclusive technologies in terms of tread pattern and belt construction considering a synergetic effect with compound and separation of lateral/longitudinal stiffness have been developed and evaluated through both numerical simulations and experimental analysis. As a result, appreciable improvements in terms of ologic's advantages have been observed. By using the exclusive technologies, an intermediate size of ologic tires is proposed as well for assisting adoption of ologic tires in the next generation of eco-friendly vehicles with a hope of developing a combined package of tire-suspension system and an ologic tire for making full use of ologic's advantages.
