Cab, I currently have Mickey Thompson tubes; the ones that I'm having the issue with. I've looked at Cooker, Hoosier, Jegs, Summit and a few other vendors; all seem to have the metal valve stems in the size I need.

I'll have to measure the OD of the hole and get back to everyone.

I wish I still had the wheels I sold; I would have just re-used my old tubes.

Thanks for the reply!
