"textContent": "A method for detecting a tire having a decreased internal pressure by making a relative comparison of wheel speeds of tires. The method includes a step of detecting wheel rotation information of the respective tires of the vehicle; a step of calculating wheel speeds based on the detected wheel rotation information; a step of calculating a decreased pressure determination value; and a step of determining a tire having a decreased internal pressure. The method further comprises a step of setting a threshold value, in which the the predetermined threshold value is set based on a decreased pressure sensitivity calculated from a relation between a load sensitivity and a decreased pressure sensitivity during vehicle turning with regard to tires that is calculated in advance and a load sensitivity obtained through a turning running during initialization.",
