Can I be a pain and add a question to this thread???
I am new to towing a TT this year, and felt it to be a good idea to start off right away with a pressure monitoring system. I bought and installed the tire tracker system and am quite impressed with it.
When I accepted the TT from the dealer I asked about tire pressure and was told to "leave the pressure where it was" by the guy that has now been fired!!!! Where it was turned out to be around 70PSI. Then on inspecting the tires I find that they say MAX 50PSI. Needless to say, i reduced the pressures to the max.
I was also informed that these tires were filled with Nitrogen not air.
So in the last few trips, I have had to remove air before departing because the pressures seem to creep up closer to the 54PSI level (Cold)......
I am not familiar with Nitrogen in tires.....could this be why my pressures seem to migrate upward? even though the outdoor weather temperatures have not??
