The paper describes a finite element model for steady state rolling tire analysis. The model,

which is improved in comparison to earlier models created by the authors, enables a larger

number of analyses to be conducted in less time and with greater accuracy. The descriptions of

model structure and model building procedure are given, followed by the algorithm according

to which the improvement of future tire performance may be achieved. It includes the analyses

of inflation, vertical loading and steady state rolling. Example analysis of each of mentioned

types and typical results are given in the last part of the paper.
