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 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…
