traction tires for bachmann steam

[jerry20]

My class J threw a tire,and I cant  seem to find anything to fit it, I've tried the calumet tires, (didn't work), then I tried the stewart tires for diesels, thinking by stretching then further they might fit the groove better, but they all seem to protrude to far out of the groove, raising the rest of the drivers far enough to cause it to derail.  Anybody know where to get tires to fit bachmann steam? Mr. bachmann? Or any body else? Would appreciate it very much.
