Anyone ever had the valve stem eject from a Firestone natural rubber tube? Thought these were supposed to be the creme de la creme of tire tubes...
The tube is about 3 years old, filled with CaCl fluid. It had recently started weeping around the valve stem, and we knew something was up.
The tire was a little soft the other morning. Dad goes to air it up so he could spread one last load of manure before he took the tractor off the spreader to fix the tire. The whole valve stem shot out across the yard.
We pulled the tube out yesterday expecting it to be split or have a hole in it. We used a blow gun to inflate the tube up to ridiculous size, and not one single pinhole or leak anywhere.
The only problem was the metal valve stem came unbonded from the rubber tube!
