That's exactly what we did, except we sent it out to be balanced in a shop with specific equipment. They balance car and truck tires so a request to dynamic balance a small tire at 1500 RPM sounded a bit weird to them. Only cost $20 dollars, though. With guarantee (one of the tires was out of balance after a while so they redid it)!!
I think the machine uses lasers to detect the tire wobble, but I'm not sure. Anyway, it's a fancy machine.

That's probably not a solution now that your robot is gone, but you can try the low tech method described above. It won't be perfect, though, since you probably won't be able to balance it up to the high rotation speed we normally use in FIRST shooters.
