Detailed tweaks to the regulations, which will have a dramatic impact on strategy and spectacle, have been tabled for discussion at next month's F1 Strategy Group meeting. The rules, if accepted and then agreed by the F1 Commission and FIA's World Motor Sport Council, will demand that each driver must stop twice during the race to fit new tires.
Furthermore, drivers will not be allowed to use the 'prime' specification of tires for more than 50 percent of the race distance, while the option compound will not be allowed to be used for more than 30 percent of the race distance.
