Hi and welcome to the group.

One of the best parts sources happens to be in Utah: www.aircooled.net
They may have some club info too, I don't know. Email links on their
website. They do come here to talk too occasionally

Rotating the tires is a good idea. There is very little else that could
be wrong with the rear. Maybe the tire is out of round, or has some
other hard to find damage in the internal structure, causing a raised
spot on the tread surface. A tire like that will usually die a horrible,
sudden death, when the tread separates from the body of the tire,
exposing the steel belts and letting air out. Replace the tire, maybe
they even have a warranty on them since they are so new, even if you
didn't opt for an extra warranty package when you bought them.
It doesn't sound like a balancing problem.
