  2. 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

  3. 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

  4. 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 G-rated tyre

  5. 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

  6. 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

  7. Live Demos Rolling resistance Roll from standing start over ¼ mile Wet braking 50mph then braking onto a wet surface Telematics Satellite data logging Personalised results Group averages Book in Talk to one of the Continental, Michelin or Yokohama representatives
