Nope. That heat has to go through the tire, which is MUCH thicker and shows no sign of wear. Enough heat to fail the tube would cause the tire to actually melt. The heat would transfer much faster through the steel wheel. Also, the brake pads are much larger than the small areas of defect. The defect areas seem to have tight boundaries.
And the most definite reason that's not it: For this failure, all three areas are on the valve side of the tube - away from the brakes. I didn't save the tube from my earlier failure.

We have a new theory from another board, and it fits the facts:
The tube & tire are new. The tire may have come with 3 rectangular stickers on the inside that the A&P removed. The adhesive residue remained. The adhesive is corrosive to the tube rubber but not the tire rubber. That's why they're all the same shape. A poster on another board said that my failures looked liked ones he had that he was able to conclusively track to stickers on the inside of the tire.

Quote:
I guess the take-away is leave the stickers on inside the tires, or remove them and thoroughly clean any residue with Goof-Off or such! |

Had this same issue a few months back. New tire and tube installed in Jan. Failed in August. Checked for stickers and/or residue, nothing. Heat should not have been any factor as rolled out. Taxi in and noticed tire going down when putting away.

About those stickers in tires...
