The BB-8 wheel is comprised of two parts. The inside wheel is an Earth like tire with an infill design of Honeycombs to prevent wear-and-tear and help the rover go over the softer sandy areas that the outer tire would struggle with. The outer wheel is a metal spring tire to help reduce impact and further reduce wear on the grousers of the inside tire. The whole wheel is circular in shape to prevent damage from loose debris that might flip up while the rover is on the move.
