According to the producer’s information Michelin Alpin A4 205/60 R15 91 H has the following parameters:
According to WE Directive no. 1222/2009, from November 2012, all tyres will display a new tyre label ticket. Manufacturers of tyres for cars, light and heavy trucks must specify fuel consumption, wet grip and noise classification of the product by means of a sticker or a label.

Fuel efficiency (rolling resistance)
Fuel efficiency is rated from A to G on a color-coded scale.
A class (green) stands for the highest fuel efficiency rating (=the lowest rolling resistance).
G class (red) marks the lowest fuel efficiency rating (= the highest rolling resistance). Rolling resistance influences fuel consumption and fumes emission, thus the higher the resistance, the lower fuel consumption and exhaust fumes emission.
-
Wet grip
Wet grip’ is the tyre’s ability to adhere to the road in wet conditions. The EU rating focuses only on one aspect of wet grip – the wet braking performance of the tyre. Wet grip is rated from A to F:
A class stands for the best braking performance, whereas G class stands for the worst breaking performance. It is one of the crucial parameters influencing the road safety.
-
Noise
Tyres contribute to the amount of pass-by noise a vehicle generates. It is reflected by means of wave symbols: 1 black wave stands for quiet tyres, whereas 3 waves signify that the tyre is noisy. The EU rating measures the external noise emissions of the tyre in decibels (dB). Choosing a tyre with a good noise rating will lower the impact of your driving on the surrounding environment.
