An apparatus and a method are provided for ascertaining the relative position of a first tire and a second tire in a multiple tire. The apparatus may include a first electromechanical transducer providing a first sensor signal indicating a contact area length of the first tire in the multiple tire, and a second electromechanical transducer providing a second sensor signal indicating a contact area length of the second tire in the multiple tire. The apparatus includes a reception unit configured for receiving the first and second sensor signals; a contact area characteristic ascertainment unit ascertaining the contact area lengths characteristic of the first and second tires based on the first and second sensor signals; and a position finding unit ascertaining the position of the first tire relative to the second tire by evaluating the contact length characteristics of the first and second tires during cornering.
