The wet grip rating indicates how well the tire will perform in wet conditions, with performance graded from class A down to class E. A high grade means short braking distances on wet roads.
Reduced rolling resistance saves fuel and cuts CO2 emissions. Class A tires deliver the best fuel efficiency, with fuel consumption increasing for each subsequent class through to E.
This is the external rolling noise generated by the tire, measured in decibels. The label shows the noise level rated in classes from A to C.
