What is tyre labelling all about?
• Legislation
– From November this year, car, van and truck tyres [made from
1 July] must display a label that rates their fuel efficiency,
safety and external noise
• Scale
– 31.4 million cars on UK roads
– Around 30 million car tyres sold in the UK each year (over
80,000 every day)
• Who is affected?
– Motorists buying replacement tyres
– Consumers buying new vehicles

What is tyre labelling all about?
•
The label
– Rolling resistance (fuel efficiency)
– Wet braking (safety)
– External noise
•
Criteria
– Over 50 criteria are measured by tyre
manufacturers
– Why is the label useful?
– Importance of simplicity for motorists
– Other factors to consider - eg
wear/performance
•
Informed choice
– All A-G tyres are legally compliant
– Labels enable motorists to make an informed
decision

Rolling Resistance
The Test
• A machine calculates each tyre’s rolling
resistance so that accurate comparisons
can be drawn across the rating scale
What it means for motorists
• A-rated tyre could give up to 7.5%
improvement in fuel economy over a Grated tyre

Wet Grip
The Test
• Under standardised conditions, wet braking
performance is measured as a vehicle brakes from
50mph to 13mph
What it means for motorists
• More information about wet grip
• A-rated tyre could give a 30% braking distance
improvement over a G-rated tyre
• Braking from 50mph to 13mph, could be up to 18
metres shorter with A- over G-rated tyres

External Noise
The Test
• Microphone measures pass-by noise levels (in decibels) as
a vehicle passes at 50mph
Label ratings for noise
• Future targets
• Three waves = noisier (exceeds future limit – but complies
with current limit)
• Two waves = average (complies with future limit)
• One wave = low noise (3dB or more below future limit)
What it means for the environment
• Quieter towns and less motorway noise
