Bridgestone has revealed its second generation air-free concept tyre. The manufacturer said the new model features improved load-bearing capabilities, environmental design and driving performance. The tyre is “one step closer to a viable, commercially available air free tyre,” Bridgestone stated.
The Tokyo Motor Show 2013 opens to the public on 23 November, and during the press days ahead of the official start of the exhibition Bridgestone unveiled its second generation ‘air free’ concept tyre. The manufacturer says the latest improvements to the air free concept bring it one step closer to developing a viable, commercially available non-pneumatic tyre; the second generation concept features improved load-bearing capabilities plus a more ‘environmental’ design and driving performance.
Enjoying its international trade show debut at this week’s Agritechnica is a concept tyre from Michelin. The manufacturer says it has “reinvented” agricultural tyre tread with the design of the new tyre and while the company says “only the future will tell whether or not this concept tyre will one day be brought to market” it says it may be commercially available by 2020.
It’s neither a traditional tyre, nor is it a rubber track – the latest agricultural product from Mitas, the PneuTrac, is described by its creator as “bringing together the best of both worlds.” The tyre concept displayed at the Mitas booth during Agritechnica 2013, combines a traditional pneumatic tyre with a rubber track – and the result, says Mitas, is a 53 per cent larger footprint compared with a standard tyre.
The global premiere of the Mitas “PneuTrac” concept tyre will take place at the upcoming Agritechnica fair in Germany. Mitas describes the concept tyre, which pairs a traditional pneumatic tyre with a rubber track, as revolutionary.
Dunlop has developed tyres for the new Opel Monza Concept car, revealed at the 65th International Motor Show in Frankfurt this week. Dunlop says that work on the concept tyre, in size 245/35R21, began in early 2013 and underwent a number of stages in collaboration with Opel to meet the car manufacturer’s expectations. The design features the same sleek lines found on the Monza Concept, enhancing the car’s overall look through the tyres and onto the ground.
“Dunlop and Opel design teams worked on the design and development of the tyre to ensure the tread matched the sleek shape of the car perfectly”, explains Helmut Fehl from Dunlop’s advanced design and development centre in Hanau, Germany. “Every detail of the tyre was discussed, evaluated and designed to meet the highest standards and expectations of the Opel team.”
Hankook is aiming to innovate with premieres in the fields of green tyres, performance, safety and premium original equipment, award-winning hybrids design-concepts as well as a new generation of airless, almost entirely recyclable tyres at the Korean company’s IAA stand. The 65th IAA, runs from 12 – 22 September 2013 in Frankfurt, Germany.
Bridgestone has announced its dual strategic intentions for its stand at the 65th International Motor Show for Cars in Frankfurt. The manufacturer will divide its stand between a “current zone” with its “Everywhere” brand marketing platform and premium tyre range, and a “future zone”, which will focus on concept tyres, including one made with “100 per cent sustainable material”. The show takes place on 10-22 September, and Bridgestone Europe’s 320m² stand will be located at D03 in Hall 8.
The Citroën Hybrid Air has enjoyed its world premiere at this year’s Geneva Motor Show, and the technology is expected to be in production by 2016. Based on a petrol engine and hydraulic components (engine and pump) but no battery, the French car maker states that Hybrid Air technology combines ground-breaking performance with maximum accessibility. Citroën claims the Hybrid Air demonstrator can achieve 2.9 litres of fuel per 100 kilometres, with carbon dioxide emissions capped at 68 grammes per kilometre; in comparison the Citroën C3, at the same power, uses 4.5 litres of fuel for 100 kilometres and emits 104 grammes of carbon dioxide per kilometre.
In the future we may return to the past, at least when it comes to tyre dimensions – tomorrow’s tyres may take their cues from the large diameter, thin tyres of the 1920s and 1930s. By giving tyres a larger vertical diameter and increasing their internal air pressure, it is possible to limit changes in the shape of the contact patch, the section of the tyre that comes in contact with the road. Furthermore, by optimising the structure of tyres created using this technology and using appropriate materials, a significantly lower rolling resistance coefficient can be achieved. And when these tyres are narrower than those typically used today, air resistance is also decreased.
Bridgestone Corporation’s 2012 Mid-Term Management Plan (MTP2012) leaves little scope for misinterpreting the company’s aim. In its latest plan, announced 18 October, the Japanese firm states that its ultimate goal is to become the “undisputed world number one tyre and rubber company in both name and reality.” The plan covers the five years from the start of 2013 to the end of 2017, and Bridgestone says MTP2012 reflects “changes in the operating environment” since the formulation of MTP2011.”
Yokohama Rubber Co., Ltd. has announced its participation in Tokyo Motor Show 2011, which will run from 30 November to 11 December (open to the general public from 3 December), at Tokyo Big Sight in Koto-ku, Tokyo. Yokohama will present some of its ideas, technology and activities including the firm's BluEarth eco tyre. Not only the BluEarth branded tyre series will be on show, but also other tyres developed based on the BluEarth concept. The company's latest environmental technology will also be explained, including the "nano bland compound" containing orange oil and the Airtex Advanced liner, which can substantially mitigate natural air leakage.
Last month’s IAA motor show in Germany featured numerous concept vehicles. Concept tyres also made an appearance, including Hankook’s new concept for electric and hybrid vehicles, the Kinergy Eco EV. Described by the manufacturer as a “further development” of its spring 2011-launched Kinergy Eco, the tyre shown at the IAA featured tweaked contours to reduce air drag and rolling resistance below that of its production counterpart. Hankook also notes that the Kinergy Eco EV’s 155/70 R 19 dimensions give it an “unusually large” diameter (700mm) compared to its width.
Industrial design associates, Dolton & Dex, has announced the launch of the world's first concept tyre design service. According to reports, director Bob Dolton has spent many years working on concept tyres for a number of OEMs. "More often than not, it is an area of the vehicle that designers feel they have a lack of control over," said Dolton.
Bridgestone has revealed that it will focus on its future strategy in ecology, innovation and reliability on its 284m² stand in Hall 8 at the 2011 IAA show in Frankfurt. The stand will be split into three sections, with the left devoted to ecological features, the middle and “innovation zone” and the right focused on reliability.
