Strengths: The Ecowing ES 31 is a more economical tyre than its predecessor. Its tread compound uses high dispersible micro-silica to drive more miles. Fuel consumption is lower thanks to the E-SBR tread compound and more aerodynamic shoulders, factors that reduce the rolling resistance. In terms of safety, braking distances are shorter than with the previous version. Four longitudinal grooves quickly clear water to increase grip and prevent skidding. The asymmetric tread has reinforced shoulder blocks to provide stable handling in dry conditions.
