Tire pressure sensors and 19.5" wheels

When I bought my 19.5s I had after market TPMs put in them. The ones on the Ford are a high pressure rubber stems which I didn't want even if they would work on the 19.5s. The ones I put on the 19.5s would play nice with the on board monitor sometimes and other times it would not. I have a TPM system (a Doran ) so I installed the sensors on the 19.5s and used this in place of the onboard and just ignored the light. It worked this way all the way to Alaska and back. When I got back I switched back to my stock tires and wheels as I had decided to trade the truck in.

I now have no need for 19.5s and have to figure out the best way to sell them as I now have a dually so no need for them anymore.
