John, I didn't do any Co-efficeint of friction testing, but on carpeting we had plenty of traction to push other robots around and we were very difficult to push of of the ramp. We won Clevland, runnered up at Great lakes, Seeded #2 in Newton, wonRI, and Won Sweet Repeat. I would say the wheel combonation was very effective for us this year. Also, Teams 47 and 48 also used the Mongoose wheel combo and both teams seemed to have good traction. Sorry I don't have anymore technical info on the tires, I don't care why it works, it just does! LOL
Now if we want to get into the finer points of the trans or chasis fabrication or technical data of a 700 HP Big Block Chevy, now were talking!
