The centre wheels were lowered. There isn't a traction benefit from running wheels like that, they are arranged like that to gain the greatest stability with the octagonal (or hexagonal in 2007) frame design. The frame design is the real magic of that design; when teams try to push or pin SwampThing (or if the robot just runs into something), the opposing robot/object tends to get diverted off to the side instead of heavily impeding their motion.
