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.

You forgot, now that you live high in Las Vegas..... they're snow tires!!

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

Or maybe drag slicks are just too expensive. g
