  • TIRE INSERT FOR A TIRE OF A MODEL VEHICLE
    Publication number: 20210170292
    Abstract: A tire insert for a tire of a model vehicle. The tire insert is made of a closed-cell foam and includes an outer surface, an inner surface, two perforated disk surfaces, and at least one cushioning cavity having at least one opening. The two perforated disk surfaces connect the outer surface with the inner surface. The at least one opening is arranged on one or on each of the two perforated disk surfaces so that the tire insert has a defined flexibility and/or an increased flexibility. The inner surface is substantially parallel to the outer surface so that the tire insert has a form of a hollow cylinder.
