was damaged After wearing them for a few months, my TPMS detected that my tires were deflated. I went to the local gas station to fill up a tire and lo and behold the valve stem cap is sealed. I couldn't turn it at all so I checked other wheels and it was the same scenario. They are called AAA and appear to be welded to the valve stem. The car now needs to be towed to my local shop to have all the valve stems replaced for $120/wheel x 4.
