I've never touched them, but it could be comming from the fact that retreads in general take more weight.

I can recall using an old snap-on manual spin, electronic tire balancer on some retreads right in the very early 1990's. Each of those took over 8 oz. on one place to balance out!

On the other hand, I would never balance my wrinkle wall slicks. There was too much tire change or growth during a burnout or running down the track for me to beleive that any balancing I did with that old snap-on unit would actually be worth it. I guess maybe a Hunter road-force balancer might be better for those.

Non of my responses are specifically addressing your question though, so I will say this... I have found that balancing is more critical for me on the front wheels than on the back. If you can balance these Hurst wheels with a normal amount of weight, great. If you can't, I would recommend just putting them on the car and seeing if you actually notice them being out of balance.
