GRBP was established in 2018 with the transfer of responsibility for tyre regulations from GRRF (as part of the conversion of GRRF into GRVA). GRBP decided to maintain the GRB session numbering despite the name change such that the first GRBP session is number 69. GRB session 68 included discussion of tyre issues.
