Ross Brawn says F1 Pirelli need to work together to help the sport's tyre supplier offer a better compromise when it comes to its compounds.
Looking back at the recent Mexican Grand Prix, Formula 1's sporting manager noted the usual difference in performance between the frontrunners and the remainder of the field, but Brawn also underlined several drivers' cautious approach to tyre management which he felt had impacted the race.
"Apart from the usual differences in performance, tyre management was also responsible," said Brawn.
"Nico Hulkenberg, Charles Leclerc, Stoffel Vandoorne and Marcus Ericsson did just one pitstop and all four were very cautious to make it to the finish on the same tyre."
Brawn acknowledged Pirelli's "difficult challenge" by which it must guarantee a level of degradation of its rubber while also ensuring a degree of durability.
"On the one hand they have to bring tyres that degrade and make for exciting races, but on the other the drivers want to fully exploit the potential of their cars with robust rubber," explained the British engineer.
"It's not always easy to find the right compromise, so it's very important that we work together."
As it caters to the future, Formula 1 has initiated its tyre tender process which will pit incumbent Pirelli against South Korean tyre giant Hankook for the 2020-23 period.
For all the criticism often directed towards Pirelli in the past, many - like Ferrari boss Maurizio Arrivabene - believe an eventual change to a supplier with no F1 expertise would not benefit the sport.
"It's not our decision," said the Scuderia boss. "But personally I would not give up all the experience we have gained in recent years."
