Wet grip for C3 tyres: Minimum type-approval level

Document GRRF-75-02

20 June 2013

75th GRRF session (17-19 Sep 2013)

Supporting presentation to the ETRTO proposal for minimum wet-grip performance thresholds (document GRRF-73-18) to ensure that improvements in tire rolling resistance (per EU CO2 goals) do not result in inadequate wet-grip performance.

Submitted by ETRTO

75th GRRF session (17-19 Sep 2013)

7. (b) | Regulation No. 117 (Tyre rolling noise and wet grip adhesion)

26. The expert from ETRTO presented GRRF-75-02, justifying the wet grip limit values for C3 tyres specified in ECE/TRANS/WP.29/2013/66. Following a tour de table, the Chair noted that half the experts were in favour of amending the proposed limits for normal and traction tyres whilst retaining the proposed limits for snow and special use tyres, while the other half were in favour of maintaining those proposed in ECE/TRANS/WP.29/2013/66. The GRRF Vice-Chair volunteered to lead a discussion with interested experts on a proposal for GRRF at its next session. GRRF preferred to postpone the vote by WP.29 and AC.1 on ECE/TRANS/WP.29/2013/66 until their June 2014 sessions.
