An actual F1 race tyre will be near impossible to come across.
Paul Hembery has been pretty open on Twitter that all tyres are destroyed post race – even unused ones. This is to prevent other tyre manufacturers stealing their magic dust.
I’m sure Bridgestone were the same, if not even more secretive during the tyre war years.
They clearly make demo tyres or the like for display cars etc, so perhaps try your luck getting one of those.
Yep that is true. No tyres survives a race weekend, so a demo tyre must be the way to go.
I hope you have some luck with your search @australian . Maybe write Red Bull a polite email. They might have a dusty demo tyre laying around behind a fridge that fits your wheel.
