Bridgestone shows ‘Large & Narrow’ concept
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.
