1 EU Tire Label

2 April 2011 Tire Performance Label: A Global TrendTrend 2 EU World wide introduction of a tire label EU-Label for the performance in Rolling Resistance, Wet Grip and coast-by Noise. Beside EU a tire label will be introduced in USA and Japan Increased attention of the customers on Rolling Resistance and Wet Grip expected Increased impact of tire technology and tire performance on the markets expected US (in discussion)Japan

3 April 2011 Wet grip Criteria, Tests and Classes of EU Label 3 Fuel efficiency Current status of discussion Passenger cars Energy efficiency class RRC ≤ ≤ RRC ≤ ≤ RRC ≤ 9.0 Empty 9.1 ≤ RRC ≤ ≤ RRC ≤ 12.0 RRC ≥ 12.1 RRC RRC = Rolling Resistance Coefficient (coefficient between rolling force and wheel load) Influences fuel consumption Lower RRC values are better Passenger cars Wet grip class 155 ≤ WGI 140 ≤ WGI ≤ ≤ WGI ≤ 139 Empty 110 ≤ WGI ≤ 124 WGI ≤ 109 Empty WGI WGI = Wet Grip Index (improvement in % in relation to a reference tire) Stopping performance on wet roads Higher WGI values are better Exterior noise Absolute values for noise emission and grades in relation to legal limits Noise level of a rolling tire measured outside the car No indication for internal noise level More than 3 db below legal limit 0-3 db below legal limit Exceeding limits (not allowed after June, 2016)

4 April 2011 Ratings of Fuel Savings per Label Class 4 Fuel saving per label class (based on example of Ø 6.6 l fuel consumption vehicle). Empty Saving potential between 0.10 and 0.15 l/100 km per class l l l l l

5 April 2011 Overview of EU Wet Grip Label Regulations 5 EU Regulations UN ECE Regulation 1222 Introduction July 2012 for production November 2012 for sales Wet grip class 155 ≤ WGI 140 ≤ WGI ≤ ≤ WGI ≤ 139 Empty 110 ≤ WGI ≤ 124 WGI ≤ 109 Empty WGI Tire Label (wet grip class) UN ECE Regulation 117 Introduction November 2012 for new tires November 2013 for new vehicle types November 2014 for all tires Type Approval (minimum wet-level) Category of use (Class C1 tires) Wet Grip Index (G) Valid from November 1 st, 2012 Snow tire with a speed symbol „Q“ or below, indicating a maximum permissible speed not greater than 160 km/h ≥ 0.9 (90 %) Snow tire with a speed symbol „R“ or above, plus „H“, indicating a maximum permissible speed greater than 160 km/h ≥ 1.0 (100 %) Normal (road type) tire ≥ 1.1 (110 %) E – S W R

6 April 2011 Ratings of Stopping Distance per Label Class 6 Stopping distance differences per class* (80 0 km/h). Stopping distance is growing significantly to lower wet grade level. *Depending on car and road surface + 4 to 5 m+ 5 to 6 m + More than 6 m + 3 to 4 m Empty

7 April 2011 Wet Grip: the Key Safety Criteria 7 Technical target conflict Fuel consumption vs. Wet grip Reduction of the braking distance can save lives! Fuel consumption [l/100km] 6.70 Braking distance [m] Collision speed [km/h] 50  Braking distance [m]

8 April 2011 EU Label Classification of Today’s EU Tire Market 8 Current status in EU tire market Wet Braking [%] 155 Rolling Resistance [c R ] * Target based on current regulation proposal 11/2010

9 April 2011 EU Label Classification of Today’s EU Tire Market 9 Current status in EU tire market Wet Braking [%] 155 Rolling Resistance [c R ] Budget * Target based on current regulation proposal 11/2010

10 April 2011 EU Label Classification of Today’s EU Tire Market 10 Current status in EU tire market Wet Braking [%] 155 Rolling Resistance [c R ] Budget Quality * Target based on current regulation proposal 11/2010

11 April 2011 EU Label Classification of Today’s EU Tire Market 11 Current status in EU tire market Wet Braking [%] 155 Rolling Resistance [c R ] Budget Quality Premium * Target based on current regulation proposal 11/2010

12 April 2011 EU Tire Label covers only 20% of Key Tire Performances 12 Tire Tests will remain the most comprehensive consumer information Tire label covers only 20 % of the tire test criteria!

13 April 2011 Comparison of EU Tire Label and Tire Tests 13 A standard tire test and EU Tire Label criteria Tire tests will keep their importance as always!
