Design of a test-rig for measuring the beading stiffness on tubeless car tires

This article describes equipment used to test this important tire parameter.

Safety in motoring is of paramount importance and vehicle manufacturers are continually improving those features of cars which relate to safety. The tires on a car have a marked effect on its performance and it is important that the tires have an adequate stiffness in the tire beading to prevent the tire from losing contact with the wheel rim. IS the beading is made too stiff though, the tire will be very difficult to fit.
