Tyre Type Approval Requirements in detail

Rolling resistance requirements

The Regulation requires reductions in tyre rolling resistance levels in 2 different stages to be introduced in November 2012 and in November 2016.

For the first time, by setting lower rolling resistance requirements also for trucks tyres, the EU is anticipating CO2 provisions beyond the current European automotive policy targets:


Tyre pressure monitoring systems (TPMS)

Mandatory installation of accurate tyre pressure monitoring systems will apply from November 2012 to passenger cars. The technical specifications were expected to be published in the course of 2010 through a commission Regulation (Comitology procedure).


Wet grip requirements

The Regulation sets minimum levels for passenger car tyre wet grip performance, helping to secure minimum braking properties, in conformity with the provision already present into UNECE Regulation 117.

For Class C1 tyres

The wet grip performance will be based on a procedure that compares either peak brake force coefficient ("pbfc") or mean fully developed deceleration ("mfdd") against values achieved by a standard reference test tyre (SRTT).  The relative performance shall be indicated by a wet grip index (G).


New rolling noise limits

The first tyre road noise limits were set within the EU Directive 2001/43/EC. The new limits in rolling noise of tyres are shown below:

The Regulation is directly applicable in all the Member States, creating a level playing field in the EU.
