Abstract: A tire inspection apparatus for detecting defects in tubeless truck tires. The apparatus includes a support base having first, second and third supports, the first and third supports being pivotable between a first position and a second position. A wheel assembly is rotatably supported on each of the first and third supports of the support base with each wheel assembly having an upper portion and a removably interconnected, axially aligned second portion. A connector arrangement is provided on each wheel assembly for removably interconnecting together the first and second portions of the assembly and a lifting apparatus is mounted on the second support of the support base for lifting the first portion of the wheel assembly and for moving the first portion of the wheel assembly into and out of alignment with the second portion of the wheel assembly.
