Nordic tyre manufacturer Nokian has claimed the coveted title of the world's first A energy rated winter tyre. Designed initially specifically for the new BMW i3 electric tyre, the cold weather tyre experts will now continue with developments for further sizes.
According to tests, the Nokian Hakkapeliitta R2 can reduce the rolling resistance of electric vehicles by up to a further 30%. The energy savings gained from the lower rolling resistance increase the vehicle's range.
Tyre sizes for electric cars are very different to what we've grown accustomed to. The Nokian Hakkap winter comes in size 155/70R19 84 Q. Narrow tyres with very large wheels and low profiles are set to become the norm. For city and extra urben use, these tyres dramatically reduce rolling resistance with a very small contact patch with the road surface.
