ABSTRACT:
A tire measuring device includes a first and second telescopic arm slidably attached together. The tire measuring device further includes a pair of handles, each disposed on one end of a rod for enabling a person to manipulate and transport the tire measuring device. A roller is disposed on an opposite end of each rod for rolling against a tire during the measurement process. The handles and rollers are detachably attached to the rods by use of grooves and ball set screws. A measuring instrument, such as a digital readout mechanism and a measurement track, is attached to at least one of the first and second telescopic arms for accurately and repeatably indicating a measurement of the tire. A guard is attached to the tire measuring device for providing protection to the measuring instrument. The first telescopic arm has a plurality of reference markings, and the second telescopic arm has a zero reference marking for alignment with the reference marking of the first telescopic arm to set a starting reference point for the tire measuring device. A pin may be inserted into apertures aligned with the reference markings for facilitating alignment of the reference markings. The components of the tire measuring device may be detached and housed within a case during storage.
