Then there was the mixed pneumatic/normal wheel setup 330 used back in '04 to climb a 6" step. 12" pneumatic Skyway wheels, 6" normal ones. The normal wheels were in front, with a sloped frame to get them up to where they could get a grip. The 12" wheels drove the robot while the 6" ones got to a grip, then the 12" did their climb and up the robot went. It wasn't very fast--but it didn't need to be; that climb was autonomous and if all went well, the robot would spend all but auto and the 15 seconds or so after that hanging around in scoring position.
