EU Regulation 1222/2009 will apply from 1st November 2012 for all passenger car, light and heavy commercial vehicles tyres produced from 1st July 2012 (Date of Production Code "2712").
The goal is to improve the safety, the economic and environmental efficiency of road transport by promoting fuel-efficient (related to rolling resistance) and safe tyres (related to wet braking) with low noise levels. This Regulation allows end-users to make more informed choices when purchasing tyres by considering this information along with other factors normally considered during the purchasing decision process.
reduce fuel consumption
fuel efficiencyassociated to the tyre's rolling resistance.
Rolling Restistance is a force acting opposite to the direction of travel when the tyre is rolling. Considering that tyres contribute up to 20% of the overall fuel consumption for a car and up to 35% for a truck, it is important to reach low Rolling Resistance values.
Let's understand how it works: due to the vehicle load, the tyre is deformed in the contact area with the road surface dissipating energy in the form of heat. The higher the deformation, the higher the rolling resistance and consequently more fuel consumption and CO2 emissions.
In the EU tyre Regulation label, rolling resistance is expressed in grades, ranging from A (best grading) to F for industrial vehicles and G for cars (worst grading). THE DIFFERENCE BETWEEN A "C" TYRE AND A "B" TYRE MEANS A REDUCTION OR INCREASE IN FUEL CONSUMPTION OF BETWEEN 2.5% - 4.5% FOR A CAR AND 5%-8% FOR A TRUCK
Increase safety on wet
safety associatedto the tyre's wet grip.
wet grip is one of the most important safety characteristic of a tyre. Excellent grip on wet means shorter braking distances when driving in rainy weather.
There are other important parameters which are relevant for safety but wet grip was chosen as the most representative situation in order to compare different tyres. THE DIFFERENCE BETWEEN EACH GRADE MEANS AN INCREASE OR DECREASE IN STOPPING DISTANCE OF ROUGHLY 2,6 m* WHEN BRAKING FROM 50 mph.

Reduce noise emissions
External noise level(given in decibels)
Traffic noise is a relevant environmental issue determined by several factors such as:
TRAFFIC INTENSITY, VEHICLE TYPE, DRIVING STYLE AND TYRE-ROAD INTERACTION.
The value indicated in the label is not the internal noise that the driver perceives while driving, but the external one, which contributes to acoustic pollution. 3 BLACK SOUND WAVES Meets ec dir. 2001/43 limits.
