Looks like a standard tire to me

I actually thought they looked too thin too, but in the sense that it might help it look more like a hot wheels car (and a little better to look at)

Now I’m just thinking it was supposed to have wider tires and they changed that too

They are wider than most car tires, but they are also very tall. Their website says the tires are 285/65R20. Very high profile, even with 20” wheels.
