New tyre designs for cars, buses, trucks from October 1; govt issues notification

From October 1, new tyres manufactured by companies for cars, buses and trucks will have to comply with new rules that mandate requirements of rolling resistance, better wet grip and less rolling sound. With this, India will be aligned with UNECE (United Nations Economic Commission for Europe) regulations.

On Friday (July 1), the Ministry of Road Transport and Highways (MoRTH) said it has issued a notification dated 28th June 2022 with regard to this.

As per the notification, it will amend rule 95 of the Central Motor Vehicles Rules 1989. “It mandates requirements of rolling resistance, wet grip and rolling sound emissions for tyres falling under classes C1 (passenger cars) , C2 (light truck) and C3 (truck and bus), as defined in the Automotive Industry Standard (AIS) 142:2019,” the ministry said in a statement.

“The said tyres shall meet the Wet grip requirements and Stage 2 limits of Rolling Resistance and Rolling Sound Emissions, as specified in this AIS. With this regulation, India will be aligned with UNECE (United Nations Economic Commission for Europe) regulations,” it added.

As per the notification, new designs of tyres to be fitted on motor vehicles and falling under Class C1, C2 and C3 as applicable as per of AIS 142 should be implemented from October 1, 2022. And for the existing tyre designs, the date for implementation is April 1, 2023 (for rolling resistance and wet grip). For less rolling sound, the new rule comes into effect from June 1, 2023.

“Objections and suggestions received from the public in respect of the draft rules have been duly considered by the Central Government,” the ministry said. The draft rules were issued on May 17, 2021.

The rolling resistance of tyres has an impact on fuel efficiency; wet grip performance influences braking performance of tyres under wet conditions and promotes vehicular safety. The rolling sound emission relates to the sound emitted from the contact between tyres in motion and the road surface, the ministry said.
