But would it close the gaps? Would some backmarker team’s struggle with a certain tyre make them more competitive if they could use their favorite throughout? Or would it be offset by the same happening with others? What would be the relative gains? Not sure, but seems frontrunners are Ok(ish) on most tyres whereas some BM teams can have quite a drop-off on some compounds.
Also, some cars are kinder on their tyres and could perhaps benefit from running long (maybe even a whole race) without pitting, whereas others with handling issues could alleviate those with grippy tyres and instead go fast and stop more. (maybe change the fronts only)
