In the last 20-years and 3,300 hours flying my RV-6, I have NEVER balance the wheels or tires. I have used retread tires the for more than the last 10-years.
Do not waste your time or money on balancing the tires / wheels. Fly the airplane. IF there is a wheel / tire balance issue that needs balancing, you can then start thinking about balancing.
This is not the first time I have heard someone talk about balancing but is the first time I have seen more than one person say they think it is necessary.
