The present invention is a method for tire rolling simulation comprising
the steps of: setting a tire model by modeling a tire with the use of
elements capable of numerical analysis; setting a road surface model
including a road-surface matter model formed by modeling road-surface
matter forming a road surface with the use of elements that can be
numerically analyzed and can cause a volume change due to compression
which is substantially permanent; and performing a tire rolling
simulation by making the tire model get in contact with the road-surface
matter model, thereby providing the tire model with rotating conditions,
and conducting deformation calculations of the tire model and the
road-surface matter model at minute time increment intervals.
