Sandusky OH Sam's Club tire tech told me they don't install new tire valve stems unless you specifically ask. Bought new tires for my daughter because tread was low and valve stem leaked. Paid for top install including road hazard at $20 per tire. Picked up car, 2 days later flat. Make it a point to TELL them they need to replace valve stems or they won't. Still fighting with them trying to get new stems put in.
