Title:
ランフラットタイヤ
Document Type and Number:
Japanese Patent JP4942277
Kind Code:
B2
Abstract:
A runflat tire is provided that may be used in applications currently requiring a large aspect ratio tire. The runflat tire of the invention may be substituted in these applications while providing desirable ride characteristics. The runflat tire includes a sidewall with a radial portion and a cantilever portion. The cantilever portion may be fabricated by extending a sidewall insert in the axially inward direction or by extending the bead filler in the axially outward direction. In other embodiments, the cantilever sidewall portion is formed by a combination of the sidewall insert and the bead filler. The resulting runflat tire has desired durability in the uninflated operating condition while having desired ride characteristics in the inflated condition. The sidewall structure allows the tire to be used in applications presently requiring a tire with a high aspect ratio.
