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.


... maybe its to keep them from sliding around on slick wet muddy
ground.


Or maybe the lugs help keep the molded tires from collapsing?
