Abstract
An auxiliary locking brake for tandem tires is formed by upper and lower wedge members centrally joined by a threaded shaft moving the wedge members toward and away from each other for impinging confronting thread surfaces of tandem tires when disposed therebetween. Telescoping members adjustably extending between panels forming the wedge members permit fore and aft adjustment of the spacing between the wedge forming panels prior to installation of the locking device on the tires of a particular vehicle. Tire retaining flanges on the wedge members prevent lateral movement of the device in a direction parallel with the axes of tandem axles.
