This gauge reads 50 to 94 pounds for a tire that is inflated to 80 pounds. I expected accuracy, but the lack of quality control shattered that dream. I'm going to the parking lot now to buy a tire gauge and I'm going to find out if the Chinese gauge is more accurate, if not at least it's easier to return. I hope your returns department does a better job than your quality control department. Made in America used to mean something good.
