All towed motorized vehicles, such as cars, trucks and SUVs, will have either rubber or aluminum valve stems. If you have a rubber valve stem, you will need brass transmitters. If you have an aluminum valve stem, you will need aluminum transmitters.
RVs, motorhomes, 5th wheels, and trailers will all have either rubber, or solid steel, chrome, or nickel-plated valve stems, all of which work with the TireMinder brass transmitters.
All TireMinder kits come with brass transmitters. If you need aluminum transmitters, please reach out to us by phone Monday through Friday, 9 AM to 5 PM, at 772-463-6522 or email at firstname.lastname@example.org.
