A maintenance assembly for a wheel assembly of an amusement ride vehicle includes a foundational body, a wheel engagement section extending a first distance from the foundational body, and a datum section including a protrusion extending a second distance from the foundational body. The wheel engagement section is configured to contact a wheel surface of the wheel assembly, and the datum section is configured to contact a pad of the wheel assembly. Additionally, the wheel engagement section is rigidly positioned with respect to the datum section, and the second distance is greater than the first distance, such that the maintenance assembly provides a fixed distance between a surface of the datum section configured to contact the pad and a surface of the wheel engagement section configured to contact the wheel surface.

The disclosure provides a tire centering fixture including: a gear, a first rack, a second rack, a third rack, a shaft sleeve, and a guide cylinder. The first rack, the second rack, and the third rack are engaged with the gear. The gear is disposed around the shaft sleeve; the gear and the shaft sleeve are disposed on the guide cylinder. The guide cylinder includes a central cavity and a base wall. The base wall includes a central hole and a circular recess; a lower end of the shaft sleeve is in movable fit with the circular recess of the base wall, and a lower end face thereof is flush with the bottom surface of the circular recess. A locating base is disposed on the upper end face of the guide cylinder and is fixed on the guide cylinder. The locating base functions as an end cover.
