I juat got a notice in from Discount Tire. Theres a recall on valve steems supplied by Dill Air Controls. It says they're a industry-leading supplier so I bet Discount Tire are the only ones effected by this recall.
It gives details on it. The valve stem cracks and causes a loss of air.
Dill is a major supplier, it's one of the only brands we used at the tire shop, unfortunatly there is really no way to know what model # is on your car so the only thing to do is inspect for cracks or leaks and bring them to the tire shop if anything is discovered
