Are your tyres compliant when worn? Testing the new regulatory requirements
A new amendment to UNECE Regulation 117 introduces requirements for wet grip of worn tyres to assess tyre performances at the end of its life. For type approval, artificially worn tyres are generated by mechanically removing tread material (i.e. buffing). To assess how well a buffed tyre replicates a naturally worn tyre, we tested four tyre models comparing new, naturally and artificially worn samples of each model. We carried out the regulatory test and other representative dynamic maneuvers.
