Austin, a tyre is made up of various layers of rubber, fabric and steel half together by the adhesive properties of uncured rubber. It’s only in the vulcanising stage that the tyre becomes bonded together. If the vulcanisation is destroyed by excessive heat, a new tyre will delaminates in exactly the same way as a remould. Its probably more likely on a remould because the tread band is maybe not quite so well attached, but will happen to new tyres too.
