We told you previously here about the collosal number of defective Chinese-made tire valve stems rolling down American roads today. The estimated number of these

faulty values has jumped from 6 million to 20 million and is the subject of a nationwide safety alert. That's a chilling prospect for motorists since there's no easy way to identify the valve stems, and when the valves go bad it causes a blowout-like loss of air pressure, says attorney John Cummings of Laird & Cummings P.C. Cummings spoke with Ken Kalthoff at KXAS Ch. 5 about problems with alerting motorists to the hidden danger. Kalthoff's advanced this story with news that some tire retailers are notifying customers about the potential dangers caused by the valves.
