The nearly-sheared valve stem was discovered by technicians while we were having routine maintenance done at the authorized Mercedes dealership. They removed the tire and replaced the valve stem. We were told by the Service Manager that this usually happens to the rear dual wheels, not the front. We have had zip ties put on to keep the wheel "hubcaps" (beauty rings) on the wheels because they are notorious for flying…
