Correct. People have asked using the term, but the GDC uses terms like "increased traction". The rule is NOT "you can't increase your normal force", but "you can't increase your traction". Devices specifically intended for that purpose have all been outlawed already. Devices that help accomplish a game objective (namely scoring) are apparently not an issue.

Even non-tractive wheels (i.e. within a small percentage of the rover wheels) are allowed for purposes of data gathering only.
