Cheap rubber in the tubes. It is my understanding that Bratton's had a run of good tubes made.

Call Bratton's, but they had a lot of problems with their tubes used with radials. They will be straight with you, regardless.
Some people run motorcycle tubes.................

Check the valve stems for leaks. I used a clear plastic tube filled with water to check for a slow leak.
