Not an expert, but based on their narrower size and the massively reduced weight placed on them, I’d imagine bicycle tires barely contribute to this situation.
Yeah, road wear scales with mass⁴ afaik, so if the average bike with biker weighed 100kg (it doesn’t) and the average car weighed 1000kg (it doesn’t) you’d need 10000 bikes to make as much impact as that one car. Since cyclists are generally lighter and cars heavier, the ratio is much higher.
I would also imagine that the lower speeds and acceleration a cycle is involved in contributes—the tyre just isn’t subjected to as much force.
