This document discusses various types of tire testing that manufacturers use to ensure tire quality and safety compliance. It describes indoor and outdoor tire testing as well as specific tests like bead compression, carcass strength, rolling resistance, wet/dry grip, noise, and stopping distance. Several tire testing machines are introduced that can perform stiffness, footprint, and electrical resistance tests or subject tires to lateral, radial, torsional, and tangential forces at high speeds. Load distribution and wear patterns are also evaluated.

• This test is used to test the response of the
tire when subjected to high speed.
• The tire mounted to the machine is
subjected to 4 forces namely:
• Lateral
• Radial
• Torsional
• Tangential

7. • This test is used to test load distribution at
the footprint area
• The load distribution image is taken using
a camera.
• The highest load carrying area is where
wearing of tire starts first.

8. Silica filled tires tend to conduct electricity.
This test method covers the measurement
of the electrical resistance between the
wheel of a mounted and inflated tire-wheel
assembly and a flat conducting surface in
loaded contact with the tire.

9. • In this test we check how much force is
acted on the bead area.
• The machine consists of a rim on to which
the tire is mounted, it is important that
the rim is of the appropriate size for the
tire, else air leakage will occur.

acted on the bead area.
• Significance: Puncture resistance
• Load penetrated through the tread
section.

13. • The machine is same as the bead
compression test.
• This test checks at how much load the
bead comes off the rim.
• This test is required to understand the
speed limit of the tire ie. when it fails.

14. • Amount of energy required to roll the tire.
• Also helps in identifying mileage.
• Machine consists of a torque sensor which
provides energy to the tire to rotate.

tire is exactly according to specification,
specified by the tire engineering
technologists.
