Abstract
Official abstract text for this publication.
A tire including a circular tire frame formed of a resin material that includes a thermoplastic resin and fibers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tire, comprising a circular tire frame formed of a resin material that includes a thermoplastic resin and fibers, wherein the content of the fibers in the resin material is from 1% by mass to 10% by mass with respect to the total mass of the resin material, and the fibers have a length (L) of from 5 mm to 10 mm and a diameter (D) of from 7 μm to 30 μm; wherein the tire is a pneumatic tire and the tire frame has a pair of bead portions removably contacting a pair of bead seats and a pair of rim flanges when the tire is fitted to a wheel rim, a pair of side portions respectively extending radially outwardly from the bead portions, and a crown portion connecting together the radially outer ends of the pair of side portions, and wherein the fibers are aliphatic polyamide fibers. 2. The tire of claim 1 , wherein the fibers have a ratio (L/D) of the length (L) to the diameter (D) of from 50 to 1000. 3. The tire of claim 1 , wherein the thermoplastic resin is at least one selected from the group consisting of a thermoplastic polyurethane-based elastomer, a thermoplastic polyamide-based elastomer, a thermoplastic polyolefin-based elastomer, a thermoplastic polystyrene-based elastomer, and a thermoplastic polyester-based elastomer. 4. The tire of claim 1 , wherein the thermoplastic resin is at least one selected from the group consisting of a thermoplastic polyamide-based elastomer and a thermoplastic polyester-based elastomer.
