The agenda includes welcome and opening remarks, introduction of participants and organizations, adoption of the draft agenda, review of minutes from the 13th session of June 2026, review of Terms of Reference from GRBP 78th Session (GRBP-78-13), UN R51 matters, review of report to GRBP, and determination of the date and place of the next meeting, scheduled for 20–22 October in Barcelona, Spain.
The 76th SLR session (4–6 February 2026) reviewed and improved baseline documents for Regulations 48, 53, 74, and 86 for Stage 2/Step 2 submission to GRE-94 as informal documents. SLR approved simplification of paragraphs 6.×.4. and 6.×.5. in Reg. 48 and agreed on technological neutrality amendments to Reg. 48 and a compromise text for Reg. 149. SLR approved a compromise text on “Prohibited if not allowed” for final check at SLR-77. Discussions on apparent surface and direction indicator visibility will resume at SLR-77. Transitional Provisions for the 10 series will be reviewed at SLR-77. The 77th, 78th, and 79th meetings are scheduled for April, June, and September 2026.
The agenda includes adoption of previous session reports, correction of errors in Regulation 150-01, improvement of direction indicator visibility, rearrangement of lamp provisions in Regulation 48, consistency checks for geometric visibility angles, baseline documents for Regulations 48, 53, 74, and 86, review of transitional provisions, discussion of apparent surface definitions, and submission preparation for GRE-95.
The A-LCA IWG will not submit a Mutual Resolution for adoption at the October 2026 GRPE session; instead, a status report will be presented to GRPE. Work towards completion of the methodology should continue and a revision of the Terms of Reference will be prepared. After the 95th GRPE session in October, an Information/Technical Exchange phase will start with continuation of technical meetings at reduced frequency and organisation of dedicated technical sessions only when required. Due to scaling back of A-LCA’s activities, SG2 activities will be suspended from October.
A two-day brainstorming session will be held in Brussels during October 8-9, 2026. The session aims to address the lack of a concrete test method solution for C3 tyre abrasion by reflecting on innovative test method ideas not bound to existing C1 and C2 approaches, brainstorming phased introduction of tyre abrasion requirements across C3 tyre segments, and optimising resources to reduce testing burden. Day 1 will address C3 market complexities and tyre segmentation across duty cycles; Day 2 will cover methodological ideation, funding and resource allocation, and review of the C2 test campaign before the February 2027 working document.
The Task Force on Tyre Abrasion completed work on the UN Regulation on tyre abrasion for C1 tyres and is launching C2 work. UN R186 on tyre abrasion for C1 tyres was adopted at WP.29’s 199th session in June 2026, with a two-stage implementation approach beginning 30 June 2028. C2 test method development is ongoing with an Informal Document to be submitted to GRBP in February 2027 instead of September 2026. C3 tyres will undergo a brainstorming session in October 2026 before commencing testing.
