Due to new developments in design and manufacture, runflat tires are becoming increasingly popular. Runflats offer added safety and convenience, enabling a driver to travel at least 80 kilometers at 80 km/h without having to stop to change a deflated tire.
Runflat tires have a thicker and stiffer sidewall, to provide support when the air pressure is gone.
A flat tire generates a lot of heat, resulting in a steep increase in tire temperature. Under such conditions, thermoplastic reinforcing materials degenerate and may cause the tire to fail. Not so with rayon.

Non-thermoplastic CORDENKA® rayon yarns, due to their physical structure, feature low heat build-up and high resistance to heat and stress and are therefore the only appropriate reinforcement for state-of-the-art runflat tire types. |
