Global tyremaker Bridgestone has begun supplying BMW’s new i-series electric cars with what it markets as its “ologic” technology. The ologic tyres are larger in diameter and narrower to cover more distance in one revolution; but t has a tall sidewall. While the tyres cover more distance in a single revolution, they have less contact with the pavement by being narrower, enabling BMW’s i3 and i8 electric cars to roll farther on a single battery charge.
Meanwhile, US tyre maker Goodyear is developing a technology that enables”air maintenance” tyre systems for future applications. The system would continuously monitor tyre pressure and keep it at the correct inflation level using an automatic internal pumping device.
