If now you’re moving the goalposts to “wear per mile” then car tires win substantially over bicycle tires.
According to this source bicycle tires should be replaced after about 4,000 miles. source
Whereas according to this source an average car tire should last 50,000 miles source
The argument against bicycles vs cars, using tire wear as the metric, gets even worse when you introduce the cost of tires in bicycle vs car. You get many MANY more miles per tire per dollar on a car than you do on a bicycle.
I understand all the flaws in this comparison, but this is the metric which you introduced to be the problem to solve for.
