The Dossier Tire Management System automates tire-data collection and reporting using a new handheld tread-depth and air-pressure device called Dossier Tire Probe. Scan a vehicle’s bar code with the Pocket Dossier PDA. After scanning a particular tire, the mechanic uses Dossier Tire Probe to electronically measure the air pressure and tread depth, which is wirelessly transmitted to Pocket Dossier worn on his belt.
