Looks like a standard tire to me

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.

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
