Global Technical Regulation for Tyres Roadmap Phases 1 and 2

The roadmap outlines the progression of technical regulations for tyres, covering dimensions, markings, high-speed testing, wet grip, and more. Phase 1 focuses on passenger car tyres, while Phase 2 expands to LT/C tyres. Existing regulations and proposed modules are part of this comprehensive approach.

  1. AC.3/WP.29 Session(March 2010) Roadmap Global Technical Regulation for Tyres Phases 1 and 2

  2. Mandatory Module Dimensions Technical Marking High speed test Endurance/low pressure test Wet grip adhesion test Module A Bead unseating test Plunger energy test Proposed Module Organisation • Module B • Rolling sound emission test

  3. Approach Phase 1 • Finalise technical requirements for radial passenger car tyres • For radial LT/C tyres (up to 4536kg or 10,000lbs), existing regulations (UNECE R.54 and FMVSS 139) will be specified as contracting party set options

  4. Approach Phase 2 • Design harmonised high speed test for LT/C tyres • Finalise technical requirements for all radial tyres designed for vehicles up to 4536 kg or 10,000lbs
