  "textContent": "To provide a device for detecting whether heterogeneous tires are mounted on the respective left and right driving wheels or not and accurately detecting the decreased tire pressures. The detection device of heterogeneous tires of the present invention is equipped with a means for detecting the rotational speeds of wheels mounted on a vehicle, a means for detecting torque applied to driving wheels, and a calculation means for calculating the inclinations of regression straight lines of respective relations from relation between the rotational speed ratio of the front and rear wheels in the left side wheels of the vehicle and torque applied to driving wheels and relation between the rotational speed ratio of the front and rear wheels in the right side wheels of the vehicle and the torque, and detects that heterogeneous tires are mounted on the driving wheels by comparing the inclination of regression straight line of the relation of the left side wheels with the inclination of regression straight line of the relation of the right side wheels. The detection device of the decreased tire pressures of the present invention changes the threshold for judging tire deflation to a threshold in a case of loading heterogeneous tires when it detects that the heterogeneous tires are mounted on the driving wheels.",
