Tyre category definitions and requirements for tyre use on roads under winter conditions (Germany and BMVI)
17 Jan 2017 Working Party Informal Documents Pneumatic Tires Pneumatic Tires Uniform Provisions Concerning the Approval of Pneumatic Tyres for Motor Vehicles and their Trailers Commercial Vehicle Tyres CV Tires Uniform Provisions Concerning the Approval of Pneumatic Tyres for Commercial Vehicles and their Trailers Motorcycle and Moped Tires Motorcycle Tires Uniform Provisions Concerning the Approval of Pneumatic Tyres for Motor Cycles and Mopeds Tires for Agricultural Vehicles Agricultural Tires Uniform Provisions Concerning the Approval of Pneumatic Tyres for Agricultural Vehicles and their Trailers Retreaded Tires for Commercial Vehicles CV Retreaded Tires Uniform Provisions Concerning the Approval for the Production of Retreaded Pneumatic Tyres for Commercial Vehicles and their Trailers Tire Rolling Sound Emissions, Adhesion on Wet Surfaces, and Rolling Resistance Tire Noise, Wet Adhesion, and Rolling Resistance Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or to adhesion on wet surfaces and/or to rolling resistance Retreaded Tires for Motor Vehicles Retreaded Tires Uniform Provisions Concerning the Approval for the Production of Retreaded Pneumatic Tyres for Motor Vehicles and their Trailers Germany reviews problems with applying UN specifications for the marking of winter tyres, covering disparities in definitions and performance requirements across the tyre regulations (UN R30, R54, R75, R106, R108, R109 and R117). Therefore, Germany proposes that GRRF work to resolve these disparities and offers two possible solutions: 1) Introduce the definition of "Snow tyre for use in severe snow conditions” and the related performance and marking requirements established under UN R109 and R117 into UN R30, R54, R75, R108, and (possibly) R106; 2) Amending UN R117 to extend the scope of its snow performance criteria to additional tyre classes and categories, such as special tyres (POR, MPT), all terrain (AT) tyres, and retreaded tyres for passenger cars.

Proposal for Amend. [3] to GTR No. 3 (Italy)
20 Jan 2017 Working Party Informal Documents Motorcycle Brake Systems Motorcycle Brakes Global Technical Regulation No. 3: Motorcycle Brake Systems Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78. GRRF-83-0009
GRRF-83-10
Proposal for amendments to GRRF-83-09 on amending GTR No. 3 (Canada)
22 Jan 2017 Working Party Informal Documents Motorcycle Brake Systems Motorcycle Brakes Global Technical Regulation No. 3: Motorcycle Brake Systems Proposal to delete passages under paragraph 3.1.15.2. referring to the “prediction of the vehicle deceleration” since no method for doing so is described in the regulation. Moreover, in a self-certification system, the requirement would have to be met for the actual vehicle deceleration. The proposal also substitutes switching between ABS modes for the terms "disable" and "deactivate" for greater clarity. Lastly, the proposal recommends the use of a clearly specified telltale design to signal the ABS operating status rather than to leave this function open to “…any other equivalent unequivocal indication of the disabled antilock brake system state.” GRRF-83-0010
