Minder Research TireMinder TM-A1A User Manual

Aluminum Valve Stems & Galvanic Corrosion
Please note Minder Research makes two types of transmitters, the TM-2BRASS and the TM-2ALUM. The basic
kits come with either 4 or 6 of the TM-Brass type transmitters. These will fit ALL Motor Homes (Class A, B or C),
ALL 5
th
wheel trailers and ALL towables.
TIP: you ONLY need the special TM-2ALUM if you are towing a car or light truck which already has a built in Tire
Pressure Monitoring System (TPMS).
 These will usually be 2007 or newer (as mandated).
 These valve stems will be dull silver (vs. the shiny silver on your motor home).
 The shiny ones are either stainless steel or chrome plated brass and do not require special transmitters.
 Don’t bother with the “magnet test.” Most stainless steel is not magnetic.
 What you are avoiding here is called “galvanic corrosion.” This happens when dissimilar metals come
into contact for a period of time. Moisture (especially if salty) will cause the two metals to become so
corroded that they cannot be separated.
