TYRE LABELLING
Which information do you get from the tyre label?
The label has 3 tyre performance indicators:
Fuel efficiency
Wet grip
Exterior noise level

FUEL EFFICIENCY
Fuel consumption is influenced by the rolling resistance of the tyres caused by tyre
deformation when rotating, resulting in energy losses in the form of heat. The higher
the deformation, the higher the tyre rolling resistance and consequently the more fuel
is required to move the vehicle forward. In other words, lower rolling resistance means
lower fuel consumption and therefore lower vehicle emissions, including CO2.
The new label will display different grades in “rolling resistance” where A is the most “fuel
efficient” and G the least efficient in class. The black arrow next to the grading (A to G)
indicates the performance level of the product.
A
WET GRIP
The most important role of a tyre is to provide safety - in all weather conditions. Wet
traction or grip is one of the most important performance characteristics of any tyre.
There is typically a performance trade-off when combining noise, fuel efficiency and
safety performances like wet grip. The labelling will allow customers to prioritize for
themselves their preferred performances.
The label will display a range of 7 grades where tyres with an “A” provide the highest
levels of wet grip and “G” the lowest.
EXTERIOR NOISE LEVEL
Exterior tyre noise levels are split into 3 categories and measured in decibel (dB) in
comparison with the new European tyre exterior noise levels to be introduced until
2016.
One black sound wave = 3dB less than the future tighter European limit
Two black sound waves = already compliant with the future European limit
Tree black sound waves = compliant with the current European limit
6.4
