1972 Dodge Colt

One of my slicks went flat sitting on jack stands.
Took the tube out and the valve stem has become un-bonded from the tube.
I took it back to Summit, "Tough Shix", no returns for any reason.
Well Summit sucks on that one.
I contacted Hoosier customer service, waiting on a reply.
Never turned a tire.

As long as I have dealt with tires, I have never seen that. It has to be a factory defect. Did you try going up the ladder at Summit? I would.
