A tube includes a structural ply wrapped around an axis of the tube, and adhesive which adheres an outer surface of the structural ply to an inner surface. The inner surface is part of the structural ply, or it is part of a second ply of the tube. The outer surface confronts the inner surface, and the adhesive is arranged in a predetermined pattern so that only a predetermined percentage of the outer surface is substantially adhered to the inner surface (e.g., the tube is only "partially adhered"). The predetermined pattern can include three or more stripes of the adhesive, and the predetermined percentage can be substantially less than 100%. The predetermined pattern is preferably provided by apparatus for applying and/or arranging the adhesive on the ply in a predetermined pattern prior to the ply being formed into the tube.
