It was confirmed on Thursday by the FIM that with immediate effect – in time for this weekend’s Cardion ab Grand Prix Ceské republiky – the tyre regulations for the MotoGP class would change.
Bridgestone’s preview of the Brno round explained the new regulations, which will see riders offered a greater choice of softer compounds, and the tyre manufacturer’s press officer Tom Tremayne detailed the changes in an interview with motogp.com which you can watch in the attached video.
“Bridgestone has worked very closely with the FIM, Dorna, the riders and the teams to bring about a raft of regulation changes to the tyre allocation system,” said Tremayne. “This means that instead of riders receiving eight front slick tyres of two compounds, they now get nine (tyres) of three compounds with a softer compound being introduced.”
“They still get ten rear slick tyres, of two compounds, but these two rear compounds have been made softer and they also get a choice now of the compound split – so five and five, or six of one and four of the other. This is specifically to address the issue of warm-up performance and to answer the requests and comments of riders in the last six months or so.”
