Tread Rubber

An uncured compound of natural or synthetic rubber, or a combination of both. It is procured in specified cross-sectional shape and size, in bulk form, or cut to specific length. The material is used for recapping, retreading, or sectional tread repair on a pneumatic tire, solid rubber tire, track shoe, or the like, by a vulcanizing process. For material used as filler, padding or stripping stock, see padding stock, tire repair.
