In both areas, the axle, it is line contact, the ground, it is line contact, So friction is reduced by line contact, or in other words a great reduction in contact area.

A toboggan has huge contact area a steeel wheel line contact a tire, kind of a bulge area contact.

Wheels reduce friction by decreasing the contact area between two surfaces and providing a continuous smooth contact surface.
