As Nissan neared completion of its ZEOD RC electric racer, the automaker approached Michelin with a challenge: make us some racing tires with low rolling resistance that also have a high level of grip.
The idea of reducing the rolling resistance of tires to improve efficiency is certainly not a new one. Tire manufacturers have been making improvements in this area for years. Most electric and hybrid vehicles use extremely low rolling resistance tires in order to cut rolling drag to a bare minimum. A new proposal from the European Commission would make these types of tires mandatory beginning in 2012. The proposal would set the maximum drag for new tires limited to 12kg/tonne in 2012, and then
