Abstract: Through the theory analysis of the tire steady state temperature field, the conception of the high temperature dot region of the tire temperature field is established, and through the example calculation , the description of the tire high temperature dot region is given. The idea of burying subminiature temperature sensors at the tire high temperature dot region is put forward. It will help people understand the instance of the tire heat and avoid tire high speed running at its critical temperature, thus preventing automobile happening burst tire.

Key words: Automobile tire, Example calculation, High temperature dot region Theory analysis
