  • Patent number: 4940445
    Abstract: A tire and method of making a tire by attaching a rubber material to a foam core to form an intermediate composite, placing the intermediate composite in mold, then heat during the composite so that the rubber fills the mold and fuses to the surface of the foam core. The tire can be made on a wheel by gluing a foam strip around the wheel, then sanding the foam to a desired tolerance, gluing with rubber cement at least one layer of the rubber material and then curing at a temperature between 180 and 300 degrees Fahrenheit for 40 to 60 minutes. For small scale tires such as those used on remotely operated race cars, the tires are preferably partially cured to increase traction.
