“This winter we reanalysed all the data from last year and redid all the severity tests with circuit-by-circuit simulations,” Michelin motorsport boss Piero Taramasso said.
“After this process we decided to reduce the pressure value from 1.88 to 1.80 bar.
“This will give a little more leeway to the engineers and riders, who will be able to stay between 1.8 and 2.1, having a good range to get the front pressures under control.
“In return, however, we have asked to stick to it for 60 percent of the Sunday race distance and not 50 percent like last year, because we take a little more risk.
“This news was well received by the organisers, teams and drivers. It will be like this starting with the Qatar test and it will be like this throughout the season.”
