Also, high traction normal wheels can get a mu of 1.2+, whereas omnis are around 1.0 (assuming AM omnis... I guess with custom one you could get better traction, but your options still are probably not going to be as broad as with normal wheels).

Actually, that's not exactly what happens. Really, only four wheels are fully on the ground at any one time. The "extras" just kind of skim along. How much they help is determined by the weight distribution and the drop of the center wheel. In a turn, you might only have two wheels down.
