the size obviously impacts how much they can communicate , tires are the data recording device, just like a cd. its like how some cd's can hold 500mbs , some can hold 500gbs. if you made a giant cd (like 5 meters wide) you could store like 5000000terrabytes on it, the same goes for tires.

larger tires hold more data. airplane tires hold the most. they make the loudest noise on pavement, so the message goes the farthest. ask the illuminati.
