I'm thinking there might be 3 possible fixes for this issue.
1) you can try using a clear nail polish or jewelry stuff similar to nail polish. The jewelry stuff is used to brush on rings to keep the ring from discoloring your finger. I got some
HERE2) use a small piece of plastic wrap as a barrier over the wheel to separate the tire from the wheel or
3) use a thin layer of aluminum foil as a barrier between the tire and wheel.
The best thing to do is try each one on a wheel (3 wheels total) to see which one would be the best. That way you'll know before you put all the tires on. Also if you get the jewelry stuff be sure it's sat for at least 24 hours to cure and that way you can see if it reacts with the wheel, try on an inside wheel that isn't seen easily. The only other thing I can think of is to see what Chuck might be able to do for you as they may have some ideas as well!!
