FIM press release:
The Grand Prix Commission, composed of Mr Carmelo Ezpeleta (Dorna, Chairman), Claude Danis (FIM), Hervé Poncharal (IRTA) and Takanao Tsubouchi (MSMA), with the participation of Javier Alonso (Dorna) and Mr Paul Butler (Secretary of the meeting), in a meeting held on April 11 in Doha (Qatar), decided unanimously to introduce the following amendments to the Road Racing World Championship Grand Prix Regulations.
2.9.3 For Grand Prix race events, each rider will be restricted in the quantity and specification of tyres that they may use at a single race event as follows:
During all practice sessions, warm up and the race a maximum of 20 slick tyres, specifically
Front slick tyres: 4 of Specification “A” + 4 of Specification “B” = 8 in total
Front slick tyres: 8 in total, comprised of either:
3 of specification “A” + 5 of specification “B”, or:
4 of specification “A” + 4 of specification “B”, or:
5 of specification “A” + 3 of specification “B”.
During the preceding Grand Prix (or the official test organised by Dorna/IRTA, in case of the first Grand Prix), the tyre supplier will inform the teams of the two front tyre specifications that will be available for the next Grand Prix. Teams must inform the tyre supplier of the number of each front slick specification required no later than 2 hours after the MotoGP race finish of this preceding Grand Prix (or 2 hours after the end of the final session of the official test, in case of the first Grand Prix). This allocation request will be final and no changes are permitted after this time.
Rear slick tyres: 6 of Specification “A” + 6 of Specification “B” = 12 in total
