There is one item I think we all need to be aware of. If you remove a tire from the stock wheel with the pressure monitors installed (Standard on Armada) you MUST take the nut from the valve stem and push the stem/pressure transmitter into the tire BEFORE breaking the bead on the tire. Failure to do so will probably result in damage to the transmitter. (See Bulletin #04038). After the tire is remounted you can push the sidewall in and replace the transmitter.
