How did the bad schrader valve break free from the stem?
after the "incident" i called the garage i bought the tires from. guy told me that there was a bad batch of valve stems that went around about the same time i bought my tires. the garage replaced the valve stem for free and is going to test the other 3.
all thet was left of the stem on the tire was the rubber. all metal parts were shot out. i am guessing bad glue or fit/mold or something simular.
