ABSTRACT:
Method of making a reinforced pneumatic tire in which the tire body is formed in at least two sections each including a side wall and a plurality of annular bands each including an annular reinforcing belt embedded in an elastomer. The tire sections are assembled in a mold with the annular bands of each section interleaved with the annular bands of another section and the elastomer is cured to form an integral tire body. The tire may be formed of two reinforced sections with the interleaved bands forming the annular tread section of the tires, or as three reinforced sections, including two sections each including a side wall and annular bands and a connecting section including annular bands with reinforcing belts which are interleaved with the annular bands of the other two sections to form a tread section. An annular, elastomeric tread section may be formed separately and bonded around and to the annular bands of the reinforced sections.
