HANDY GUIDE TO TYRES 5
CAR AND 4x4 TYRES.
ALWAYS CHECK THE LABEL.
Always read the label
Not the full story.
Never underestimate the importance of
reading labels. Not only are they there to
help prevent unfortunate laundry mishaps,
culinary catastrophes and fashion faux pas,
labels are an invaluable tool in helping
you make an informed decision. Hardly
surprising then, that a new EU tyre label is
being introduced in 2012 to help you make
an informed decision when buying tyres.
When does tyre labelling
come into effect?
The legislation comes into force 1st
November 2012, however many tyre
manufacturers will implement the
labels earlier.
What’s not covered?
While we’re completely in favour of the introduction of tyre
labelling, we feel it’s essential to remind you that they tell only half
of the story. So while it’s a great starting point, it’s by no means
exhaustive. It’s therefore important to look at the bigger picture.

Tyre labelling only covers fuel efficiency, wet grip and exterior noise.
Key criteria such as aquaplaning resistance, dry handling,
dry braking and high-speed stability are not covered.
W
inter conditions are not taken into consideration.
How are they rated?
The new tyre label bears more than a passing resemblance to
the ‘energy labels’ on white goods and uses the same A to G
grading. ‘A’ marks the highest performing and ‘G’ the least.
What do they cover?
Performance tyre criteria like dry handling
are not covered by the legislation.
That’s where we come in as the tyre expert,
helping you with the bigger picture.
The full story 3-15-50.
•Fuel efficiency
Tyre experts start where others stop.
•Wet grip
The EU tyre label only
specifies 3 criteria.
•External rolling noise
Why is tyre labelling being brought in?
•Increase road safety
•Help make driving cost-effective
•Reduce the environmental impact caused by tyres
Magazine independent
surveys specify 15.
What tyres does it apply to?
The labels will apply to car, 4x4, SUV, van and truck tyres. Tyres
not affected include racing tyres, professional off-road tyres, spare
tyres, vintage car tyres, retreaded tyres and motorcycle tyres.

Tyres with excellent grip in the wet have shorter braking distances on slippery roads,
essential for keeping you safe when you’re driving in rainy weather.
Did you know?
20% of a car’s
fuel consumption
is influenced
by its tyres.
These ratings are measured from the distance travelled by a car after braking at 50mph in
the wet. The difference between A and F is 18 metres (four car lengths).
A
_ G
Short to longer braking
distance in wet conditions.
D + G
This could mean:

18m
Not used.
G
*Testing according to regulation EC1222/2009.
EXTERIOR NOISE
EXPLAINED.
A tyre’s exterior noise grading is
expressed in decibels (dB) and
accompanied by one, two or three
sound waves on the label.
One wave is the best performance
and, you guessed it, three is the
worst. In fact, three bars is the
current limit, while two meets future
laws and one is a further 3dBs
below. And the quieter the tyre the
more environmentally friendly it is.
+1 wave = +3dB + double the noise
Did you know?
The difference between
A and G is 18 metres.
That’s four car lengths
or eight smart cars.
+2 waves = +6dB + four times the noise
FUEL EFFICIENCY EXPLAINED.
A rolling tyre deforms and dissipates energy, and is one of five resistive forces acting on
a vehicle. The energy that’s lost in this way is known as ‘rolling resistance’ and directly
impacts on fuel consumption and the environment. With lower rolling resistance the tyre
uses less energy, less fuel and, in turn, less CO2. A win-win-win situation if you like.
The difference between each category means a reduction or increase in fuel consumption
of between 0.42mpg and 0.56mpg for a 36mpg car.
A
A
_ G
Low to higher fuel consumption.
D
Not used.
There is a 7.5% fuel difference
between an A and G rated tyre.
G
+6 litres
Did you know?
The quieter the
tyre the more
environmentally
friendly it is.
Choosing A rated rolling resistance tyres over G rated could save a significant amount of fuel.
A few handy FAQs for you.
Q.When will tyre labelling come into effect?
A. The legislation comes into force on the 1st November 2012.
Q.Is the new legislation applicable in all
European countries?
A. The legislation will be binding and identical in all
European Member States.
Q.Will I personally have any legal obligations
under this legislation?
A. Other than driving within the normal legal requirements, you
have no obligations yourself. Those responsible for ensuring legal
obligations are met are the tyre manufacturers, tyre retailers and
vehicle suppliers and manufacturers.
Q.Does the label tell me everything
I need to know about the tyre?
A. No, the label only covers fuel efficiency, wet grip and exterior noise. To
put this into perspective, Goodyear test more than 50 parameters.
Therefore the label should be viewed as just one tool to help you to make
an informed decision.
Q.What tyres will the labels appear on?
A. The mandatory tyre labelling information will apply to car, sports utility
vehicle, van and truck tyres.
Q.How will the tyre label help me buy tyres?
The introduction of the new tyre label will allow you to make a
more informed tyre purchase by giving you information which is:
• Objective • Reliable • Comparative
