by Autocar Pro News Desk , 01 Jul 2022

The union Ministry of Road Transport and Highways on Friday issued a notification mandating  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) bringing it on par with European standards. The amendment into the regulation will become effective from October 1. 

"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" the ministry said in a statement.

The ministry said 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, it added.
