Abstract
A method of detecting a minispare tire in a vehicle having a vehicle control system. The method includes detecting a rotational velocity of each of a plurality of wheels of the vehicle; determining whether a minispare tire is mounted on the vehicle based on the rotational velocities detected at each of the plurality of wheels; adjusting the vehicle control system if a minispare tire is mounted on the vehicle; sensing a hydraulic pressure of a braking system of the vehicle; and suspending determination of whether a minispare tire is mounted on the vehicle if the hydraulic pressure exceeds a predetermined critical pressure level.
