Philadelphia drivers may be unknowingly driving around on defective valve stems. Over twenty three million valve stems from China have been recalled in fear the stems can crack.
A cracked valve stem can lead to decreased tire pressure, one of the leading causes of a tire blowout. It is extremely difficult to control a vehicle during a tire blowout and ultimately most blowouts end in a serious collision. As a way to increase profits, the Chinese manufacturer removed the chemical applied to the valve stem to prevent cracking. Unfortunately there is no way to know if your tire has a defective Chinese valve stem because there is no part number or model number stamped on the stems. Drivers can check for cracks on their valve stems by rotating the stem clockwise and checking the surface for cracks.
