I'm not the one claiming that they can, just that it's patiently false that those tyres would be competitive as you originally claimed, if you actually read what I said, I said the opposite.
The excuse that pirell could make dog shit slow tyres that lasted an entire race is just garbage. Their competitors would just make faster tyres, especially as a single stop is mandated by the two compound rule.
Your lack of understanding of how much the tyres are gamed by pirelli at the request of FIA to provide artificial cliffs for tyre life and video game style performance deltas between compounds when both are impossible irl is the problem here.
Again your lack of understanding that pirell has had some serious safety issues over multiple seasons makes a mockery of 2005 as an excuse for anybody but Michelin.
