The Conti.eContact features a completely new design which offers optimized rolling resistance and reduced fuel consumption.
Not only does the tire's construction reduce noise emissions, but the braking distance in the wet is shortened also.
The sidewall's aerodynamically optimized design reduces fuel consumption.
Secure grip in wet conditions is crucial for safe driving. Performance is graded into classes, A to G (although D and G are not currently used). The stopping distance between a class A tire and a class F tire can be as much as 18 metres.
Reduced rolling resistance saves fuel and cuts CO2 emissions. Class A tires deliver the best fuel efficiency, with each subsequent class through to G increasing fuel consumption by between 0.42 and 0.56 mpg for a car which does 36 mpg.
This is the external noise made by the tire and is measured in decibels. The more filled bars shown on the label, the louder the tires.
