UNIFORM TIRE QUALITY GRADING DATA MANAGEMENT SYSTEM (UTQG)
The system encompasses one regulation with six major areas of responsibility, i.e.; treadwear, traction, temperature resistance, tire inventory, test center schedules, and quality control. Testing under the regulation results in about 1,530 tests annually: 80 treadwear monitoring tests, 600 traction monitoring tests, 200 treadwear compliance tests, 100 traction compliance tests, 50 temperature resistance compliance tests, 250 treadwear special tests, and 250 traction special tests. The system incorporates A multiple file data base, and these files reside on 2 separate 3330-1 disk packs. Each of the 6 areas of responsibility resides in its own master file and is updated daily, weekly, or as the need arises. The files contain edit routines, sorting indexes, reformat programs, and analysis and reporting programs. As required, hardcopy plots and test results are produced. The UTQG rule requires NHTSA to provide the UTQG field test center for industry use & compliance testing. All traction and treadwear testing is done at the UTQG test center. Traction data are recorded in analog strip charts and digital printer.
