You can use a pipe-like thing to direct the air. But anything regarding pneumatic tubing, or air ultimately from the on-board compressor simply does not have enough volume to be useful in this way.

I don't know why it would violate any rules, assuming the safety aspects were covered. An increase in "weight" (more accurately, downforce) would provide more friction and therefore traction.
