They don't. Have a friend with a Pantera. Can't find tires for the stock wheels, that are worth buying, anywhere.
I remember reading that some performance tire manufacturer would make a limited run of small-diameter supercar tires every few years.

I understand they use 18 of them as well.

Yeah but even with 18 tires the way the weight distributes it is still 17000 on each dual axle at 95-100psi. You need that tire. I see 17.5 tires with that weight on that require 120psi to carry it.
On another note the original wheels would be awesome on my wall, not on my car.
