TITLE(s): TIRE TECHNICIAN (rubber tire)
Tests experimental and sample production tires to determine strength, wearability, and cause of
failure: Inflates tire on test machine, and adjusts controls to simulate road conditions, such as
speed, weight-mileage check, and roadbed. Operates test equipment, such as autographic
load-deflection recording mechanism, deflection machine, dead-load pressure gauge checking machine,
and deflection-variation measurement machine, to evaluate tire uniformity, quality, and durability.
Maintains periodic follow up on test until tire fails or has run for specified time. Cuts cross
section from test tires, new experimental tires, or actual road tested tires with power saw. Counts
bead wires and plies in cross section, verifies angle of plies with protractor, and measures
specified areas on tire to ascertain effects of testing. Records test results and prepares graphs to
compare test results.
