For the past 11 years, Toyo Tire & Rubber has engaged in research into the viability of airless tyres that deliver comparable performance to their pneumatic counterparts. The Japanese manufacturer first presented a prototype product at the Automotive Engineering Expo in May 2012 to demonstrate what it had achieved since 2006. Toyo Tires says it has since made “fundamental changes” to the structure of its airless tyres and has resolved various issues. The resulting improvements, it adds, are “substantial” and allow practical driving upon the latest generation of tyres. The company recently released its latest generation of airless concept tyre, the ‘noair’.
