A hand-held probe (10) for measuring a tire tread profile comprises a housing (20) with a slit (64) formed parallel to its major axis, a range finder (70) mounted inside the housing (20) in such a way that it can traverse much of the length of the tube while directing light from a laser through a window (60) and onto a tire surface, a bracket (50) that is carried by the proximal end of the tube to enable the user to hold the probe (10) in position against the tire, a serial port (32) for connection with a computer (40), and a handle (30) that houses the batteries for operation and an IR or RF transmitter. The IR or RF transmitter is for transmitting the tire tread profile wirelessly to a computer suitably equipped to receive IR or RF transmissions.

L'invention concerne une sonde à main (10) servant à mesurer le profil de la bande de roulement d'un pneu. La sonde comprend un boîtier (20) muni d'une fente (64) parallèle à l'axe principal du boîtier, un télémètre (70) monté à l'intérieur du boîtier (20) de manière à parcourir une grande partie de la longueur du tube tout en dirigeant une lumière émise par un laser à travers une fenêtre (60) et sur une surface du pneu, un support (50) fixé à l'extrémité proximale du tube pour permettre à l'usager de maintenir la sonde (10) en position contre le pneu, un port série (32) de raccordement à un ordinateur (40), et une poignée (30) logeant les piles d'alimentation et un émetteur à infrarouge ou radiofréquence. Ledit émetteur sert à transmettre sans fil le profil de la bande de roulement à un ordinateur configuré pour recevoir une transmission infrarouge ou radiofréquence.
