Abstract

The solid tire performance can be characterized by the contact patch. The footprint is the
particular method to achieve the contact patch between a tire and pavement. The flat surface is often equipped
to support a pressure measurement film which is pressed by the tire tread. This derivative patch illustrates
characteristic seems the probable result to predict tire performance. Practically, the contact patch happens by
the rolling tire. To understand the patch characteristic, the contact patch between the rolling tire and pavement
was studied. The 3D finite element model of solid tire which pressed on three different surfaces was developed.
The experimental footprint on the flat surface was carried out to validate the finite element model. The contact
patch of solid tire tread on the drum surface was investigated to discuss the effect of supporting floor under
various testing method. The stress distribution in the solid tire model is the exceptional criteria to clarify the
contact patch on the road. The developed models will be used to design the tire tread and pavement in the future
work.
