All towed vehicles will have either rubber (brass) or metal (aluminum) valve stems. If you have a rubber valve stem, you will need brass transmitters. If you have a metal valve stem, you will need aluminum transmitters. RVs, MotorHomes, 5TH Wheels and Trailers will all have either rubber (brass) or metal (steel, chrome, or nickel) valve stems, all of which work with the TireMinder brass transmitters.
