Zusammenfassung: | PROBLEM TO BE SOLVED: To improve durability and rigidity of a tire without significantly increasing the weight of the tire. SOLUTION: The tire 10 has a tread 14 disposed at the radial outside of a carcass 12, a sidewall 16 crossing the tread 14 by a shoulder 18, and a belt package 20 radially positioned between the carcass 12 and the tread 14. A belt reinforcing structure (belt package) 20 comprises a first cut belt layer 24 and a second cut belt layer 26 disposed at the radial outside. The width after curing of the first cut belt layer 24 generally equals to the foot print width. The first cut belt layer 24 and the second cut belt layer 26 are different in the weight per a unit width. COPYRIGHT: (C)2005,JPO&NCIPI |
