this is not true because the sensors go to sleep when not moving to save battery life. my summer tires are sitting about 10 from my truck in my garage and no issues.Store your spare rims a distance away from where your truck is normally parked, I've read the truck can pick up the signals and give problems in the readout.
speaking of battery life that's my guess on the OP having issues with motorcraft sensors failing quickly (they should last at least 5 years) is that they were old stock with old batteries, and my second guess if they were bought on Amazon or eBay is that they were cheap counterfeit.
