According to this page it's about that 25% of the whole tyre, where more than half the tyre is not rubber/synthetic rubber but other stuff.

So there is more synthetic rubber than natural rubber. But the mind-blowing thing for me here is that I kind of assumed the whole tyre was synthetic, but they are only 25% plastic and still are the biggest source of mocroplastic.

But the other stuff is nasty. Total of petrochemicals in a tyre is above 60%. That fabric, carbon black, oils, elastometers, textiles, antioxidantes and additives are all based on petroleum too
