Q stands for Quiet. Especially due to this tyre's upgraded tread pattern. Reduced noise, lower fuel consumption, wear-resistance and adaptive tread compounds are all features you can expect from the new EcoContact 6 Q.Enhanced pattern technologyEconomicalTaylor made rib and sipesNot only is it quiet but the EcoContact 6 Q uses Continental's Green Chilli 2.0, which makes the tyre capable of adapting to the road conditions. Green Chilli 2.0 is a redesigned compound that allows a more even spread of load across the tyre. This increases the strength of the bonds between the polymers within the compound, resulting in less deformation whilst driving and a decrease in rolling resistance giving you even more miles per tank.The uniquely designed asymmetric rib and sipe geometry not only reduce road noises inside the cabin but also keep you in control whatever the weather conditions.Note: Some sizes of this tyre may be available as a RunFlat tyre indicated by "RunFlat" in the speed rating drop-d
