Steve, A very good starting point to learn more about your wheels and existing upgrade information can be found in this
Big Bolt Wheels Tech Tip. Give it a thorough read, including the warnings about early RH-5 wheels (sometimes better known as Widow-Makers), before you get too much more into trying to find solutions. You can also read through some of the many recent posts in the Big Bolts forum that discuss wheel and tire upgrades/replacements and sources. Good luck on your project!
