Kobe, Japan — Sumitomo Rubber Industries, Ltd. said its fourth generation runflat tyres provide ride comfort equivalent to or better than standard tyres, while maintaining runflat performance. The company said it has adopted four proprietary technologies under the banner, "thermal control technology". These include 'CTT Profile', 'Aramid Casing', 'High Thermal Conductivity Materials' and 'Dimple Sidewall'. Together, said SRI, these have increased the driving distance of cars on flat tyres by 2.3 times, compared with the third generation runflat tyre. With those technologies, Sumitomo Rubber was able to decrease the thickness of the sidewall reinforcement layer by 30 percent and in turn reduce the tyre's overall weight by 3 percent and vertical stiffness by 6 percent, which provides ride comfort the same as or better than standard tyres.
