In contrast to the finite element method (FEM) which is widely utilized in the tire industry nowadays, some alternative methods have been proposed by academic communities since the last decade or so.  The meshfree method is one of those new methodologies.  That is originally intended to get rid of the burden of creating the mesh which is inherent in FEM, namely the meshfree method relies on the point data rather than the mesh, which makes it quite easier to discretize the geometry.  In addition to those modeling issue, it has been found that the meshfree method has several kinds of advantages over FEM in handling geometrical nonlinearities, continuities, etc.  In accordance with those emerging possibilities, the authors have been conducting research on the matter.  This paper describes the results of the authors’ preliminary research on the applicability of the meshfree method to tire analyses, which include the theoretical outline, the strategy of tire modeling, numerical results, comparisons with results of FEM, and conclusions.
