Wow that was something to go through on your rear tire, but glad to hear that Revzilla agreed to replace your tire due to inconsistencies on the thread and perhaps a defect on manufacturing. You just had to remove the tire have a shop unmount and defective tire and remount the new tire over again. At the end of the day, glad you have the peace of mind knowing that you are confident on your tires. Blessing in disguise, you also have regreased/serviced the rear end of your bike. All the best on your carb service project. FWIW, I frequent Dennis Kirk for most of my bike needs.
