I discussed that metal stem thing with both Hawkshead and Discount Tire. The Discount Tire manager pointed out that regular stems (at least the ones they use) are metal with a rubber shell. The owner of Hawkshead said the only reason he carries metal stems is that he got tired of trying to convince buyers that they don't need them.
I have used my Hawkshead HD 4 for over five years with 15 inch ST tires and 16 inch LT tires on the trailer and 17 inch LT tires on the truck with very reliable pressure and temperature readings with only the stems that Discount Tire regularly uses on truck tires.
I monitor 10 tires including both spares.
