Bead Contact Pressure Testing Machine BCM

A bead contact pressure testing machine is designed to determine the bead contact pressure of a tyre.  

Being able to mount it and its position on the rim are vital requirements of the tyre. The characteristic curve in the bead area has to be adapted frequently so that certain features of the tyre are optimised.  

It is vital that the bead is mounted over the rim flange without damaging it. Under pressurisation it has to jump over the hump and then sit evenly at the circumference of the rim flange. The height of the contact pressure and the contour of the bead have an influence on these characteristics.
