Dumb question from old Nonny for you smart guys out there to answer:

Why do the tires on gas grills usually have "lugs" on them? Why aren't
they smooth? They are just pushed and not self-driven. I bought a lawn
cart with military-style lug tires and wondered about it, also, since I
pulled it with the tractor.
