Filled tire

Abstract

Abstract PURPOSE:To obtain an inexpensive tire durable even under severe use conditions, by substituting a soft filler of low heat builed-up for air to be filled. CONSTITUTION:A tire case 1 comprises a pair of bead parts 2, 2', a pair of side wall parts 3, 3' and a tread part 4 that will be in contact with the ground, and when the bead parts 2, 2 and a wheel rim 5 are fit, a circular ring tire is obtained. The tire case 1 has no tire cord that will reinforce the tire, and is made of a resin that is reinforced with short fibers or one or more layered resins. The organic soft filler 6 has the following physical properties: a JIS hardness of 15-45 at 25-100 deg.C, an impact resilience of 50% or more at 25 deg.C and 70% or more at 100 deg.C, a stretch of 80% or more and a tear strength of 2.5kg/cm<2> or more.
