Shu,
I am not saying that inspectors will make any decisions on the use of a particular tire. We cannot tell it's use during the inspection process. I am discussing the use of certain of the mentioned methods of attempting to correct vibration and balance. Again there is no way for inspectors to determine during the process if your design is safe or not.
What I am trying to point out is that certain assumptions for high speed rotating objects may lead to unsafe conditions during play on the field. I don't want to see any team disabled by or for an unsafe condition and I certainly do not want to see anybody injured. From my calculations, many shooter designs exceed by more than 5 times the rotational speed of car tires. Even devices designed for road tires may not retain their design characteristics at your rotational speeds. Now is the time to be sure. For reference I suggest you look to videos of drag racing vehicles in the burnout box prior to a race. Be sure to take a close look at the tire profile during the burnout process.
