A unique concept for a Unique Car.
BMW has achieved a genuine milestone with the i3 & i8 electric car. Doing justice to its unprecedented levels of both efficiency and performance demanded more than just a new tyre, but an entire new tyre concept.
Bridgestone's answer came in the form of the ologic technology, which capitalises on the synergies of a large diameter coupled with a narrow tread design. The result is a tyre that delivers significant improvements in aerodynamics and rolling resistance, while still offering outstanding grip in wet weather conditions.
Combining a large diameter with a narrow tread pattern has several advantages. While the tread on smaller diameter tyres is typically inclined to excessive movement or "deformation” during driving, the larger diameter and higher belt tension significantly reduce tyre deformation and therefore conserve energy that is otherwise lost through internal friction which helps to reduce rolling resistance.
By the same token, the narrow tread concept improves aerodynamics. The most spectacular achievement, however is that these improvements do not involve a trade-off in terms of safety. The tyre’s long contact patch (relative to its narrow width), revolutionary tread design and compound still ensure outstanding grip in both wet and dry conditions.
