Abstract:

Provided is a tire, comprising: a crown, sidewalls, beads, carcass reinforcing members (30), and rubber reinforcing members (50). The beads are used to secure the tire onto a rim, the sidewalls extend radially outward from the beads and connect to the crown, the crown covers the tire along the circumference thereof, the carcass reinforcing members (30) are fixed on the beads; the rubber reinforcing members (50) are circumferentially disposed in between the carcass reinforcing members (30) and the sidewalls, and the rubber reinforcing members (50) also connect the sidewalls, the beads, and the carcass reinforcing members (30); at the same time, the various component positioning parameters involved in the bead structure are improved, and the reasonable displacement of the locations of overlap between the various components of the present invention is such that the stress in the sidewall portions is effectively dispersed, thus reducing heat buildup in the sidewall portions; low-heat-generation rubber is used as a material of the tire, reducing temperature rise in the tire during operation, and the rolling resistance of the tire can be improved.
