Job Description:

• 1) 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.

• 2) 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.

• 3) Maintains periodic follow up on test until tire fails or has run for specified time.

• 4) Cuts cross section from test tires, new experimental tires, or actual road tested tires with power saw.

• 5) 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.

• 6) Records test results and prepares graphs to compare test results.
