A chock-type wheel lock has two V-shaped cradles joined at the lowermost part of the "V" horizontally at the tire's center. A sliding bar and cylinder lock engage the cradle members together. Alternatively, a series of adjustment blocks join the cradles together for differing tire sizes. The chocks may be adjustable having an axle which slides into notches in a cradle housing to provide for multi-size tire use.

[ We claim:] [1.] A tire lock and block apparatus comprising:a left and a right cradle each having a rear wall to engage a tire's rear surface and a front panel to engage a tire's front surface, said cradles formed to engage a tire above and below its horizontal centerline at a left and right side of the tire,a lock to lock the left and right cradles together;a chock mount and chock attached to a lower curved section of each cradle;said left and right cradle each being curved in general conformance with an outer peripheral curvature of the tire above and below the horizontal centerline to form an upper curved and the lower curved section of each cradle, whereby said upper curved sections suspend said tire lock and block apparatus from an upper half of the tire above a ground surface, thereby precluding the ability to raise the tire and permit the cradles to disengage from the tire;said chock mount having a dual mode sliding engagement with the chock;said dual mode sliding engagement comprising a suspension of the chock in a first mode above the ground surface in a neutral chock position, and in a second mode when the tire presses the chock against the ground surface, to create a wedge position for the chock and a locked engagement of the cradle to the chock.
