Our rings can be used in the same way as steel bead rings as they are sufficiently stiff for automatic transfer to the build drum. It is even possible to use the same moulds as for steel bead ring tyres. The inner circumference of the aramid bead ring can be adjusted to your requirement. Different customers use slightly different inner circumferences. We normally supply samples and the customer tries them out. If they don't fit perfectly we can make the rings a little smaller or larger.
