The only way to get information on tires, not from books and theories, but from tests.The Flat Belt Tire Test Machine is an indoor tire force and moment testing machine. It allows the tire to be tested against a flat surface under dynamic conditions.

The flat surface is emulated by an electrically controlled belt-pulley assembly while the tire load is supported by an air bearing (for passenger cars loads) or a water bearing (for higher loads) that is present under the belt.

This belt-pulley assembly rests over a hydraulic shaker system that can emulate tire vertical motion and slip-angle generation in a highly dynamic fashion.

The tire stand itself is capable of changing the tire vertical load and camber angle during the test run. Alike for the wheels and rims, the machines have different sizes, following the different types and dimensions of the tires to test, including PCR, LTR, TBR and OTR.
