Thanks for the replies. Spend most time in the Carolinas but am willing to travel. Pic in above post illustrates the issue, as traditional machines don't have a large enough cone adapter. Below link from a sister forum also explains the issue in more context. Balancing bead suggestion is great assuming there are no downsides such as tire wear or noise. Thanks again.
