That's tragic. You have far more than your share of tire problems. You can of course add several hundred lbs of capacity by putting 225-D rated Marathons on your trailer with 15" wheels having the 5-bolt, 4-1/2" spacing. Not cheap but might be enough to solve your problem. As for Goodyear, methinks they are just using this to cover a move to China and to punish their U.S. union.

Of course the logical thing to do is trade for the double-axle TM3326 that your wife wants. It's quite possible your problems will persist until you do so:-). I know I shouldn't be making jokes about a serious situation but that would give you peace-of-mind.
