The invention discloses a tire structure with shape memory alloy. In the tire structure, a shape memory alloy, such as NITI alloy and the like, is employed as the cord wires inside a belted layer rubber sheets in a certain arrangement manner instead of a steel wire tire cord material in a certain ratio, , so that force distribution on tire tread and tire shoulder is improved by means of a negative thermal expansion behavior and a two-way shape memory effect of the shape memory alloy, thereby reducing steel wire stress at the end of the belted layer in the tire. The tire structure with the shape memory alloy is reduced in strain energy density at the tire shoulder of the tire, is reduced in tire use temperature and is reduced in tire shoulder crack. Meanwhile, the tire structure can enhance the stress on steel wires at the tire tread, so that a tire is improved in rolling resistance performance and service life synergistically. The tire structure can also improve stress concentration at a tire bead.
