EU Tire Label

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

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)
