摘要：For stability of a vehicle, the problem of interact-tion of tire with road is one of the most complicated tasks.For analysis of the tire and road contact, it is necessary toevaluate tire deflection features. It is rather complex taskdue to some uncertainty of tire operational conditions andsophisticated structure of the tire itself. Problem’s com-plexity is emphasized by the absence of common opinionabout tire shape till now. The geometric tire model wasdescribed by toroid [1] in earlier works, and the bandmodel was used later [2]. Modern studies of contact zonesof broad tires [3] would conform more to the ring model oflimited flexibility.
