The issue of increasing the safety of rescue vehicles to the place of emergency at the maximum possible speeds is considered. It is established that the presence of the screen impairs the heat dissipation from the frame and from all layers of the tire, which increases their thermal stress. The second layer of the breaker is the most thermally stressed. It is determined that the presence of defects also worsens the conditions of heat removal from the tire. These studies confirm the need to monitor the condition of ambulance tires. Substantiated proposals for the construction of rescue vehicles tires.
