Per R2,

The ROBOT must have a FRAME PERIMETER, contained within the BUMPER ZONE, that is comprised of fixed, non-articulated structural elements of the ROBOT. Minor protrusions no greater than ¼ in. such as bolt heads, fastener ends, and rivets are not considered part of the FRAME PERIMETER.

Wheels would not qualify as fixed, non-articulated structural elements. If I were inspecting your robot, I would not count the wheels as sufficient backing for the bumpers, but as always the only definitive answer you can get is the Q&A.
