No compromise on performance*

Ecopia tyres offer lower rolling resistance while preserving all other performance levels.

Ecopia: lower rolling resistance, less fuel*

Ecopia tyres deliver 12% improved rolling resistance compared with the previous Bridgestone line up at full tread depth.

The importance of rolling resistance (RR)

The forces that cause rolling resistance are air resistance, energy loss through friction between tyre and road, and energy loss (heat) due to internal friction between the different elements in the compound.

Energy loss through friction between tyre and road (~8%)
Air Resistance (~2%)
Energy loss (heat) due to internal friction between the different elements in the compound during repetitive internal friction between deformation of the tyre (~90%)

A few important insights about rolling resistance

RR causes between 20% and 50% of fuel consumption. At a constant 80 km/h about 40% of fuel consumption is caused by rolling resistance.
To compare RR of different tyres, the RR over the complete lifespan of the tyre needs to be examined. RR decreases as tyres become more worn. Thus, the longer the tyre lasts, the lower its average RR and the lower the fuel consumption.
