Wet grip:

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.

Fuel efficiency:

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.

Rolling noise:

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.
