Tyre label

The EU has already created a system for marking of electrical household appliances such as refrigerators, washing machines and televisions with the intent to better inform the European population about the level of their consumption.

[2] Rolling resistance is the main key factor in measuring the energy efficiency of a tyre and has direct influence on the fuel consumption of a vehicle.

'D' Grading is not used in rolling resistance grading for Passenger Cars and Light Trucks while it is used for Heavy Trucks As at January 2019, the wet grip tests for passenger car tyres (EU category C1) are specified in a 2011 amendment, Regulation No 228/2011 to the original 2009 Regulation No 1222/2009 "on the labelling of tyres with respect to fuel efficiency and other essential parameters".

Results of at least three runs of each test are combined to produce the wet grip index, yielding ratings of A - G (although D and G are not used for passenger cars), where A is the best.

When buying tyres, it is worth noting that the braking distance (in the wet) from the reference speed of 85 km/h, to a standstill, varies by something of the order of 3m from one class to the next.
