Pressure and temp ?

[wegone]

Just got back from #2 in our new trailer, great trip, so great we booked it again only longer for next year.

I had to pump up my tires after I brought the trailer home from the lot I purchased it at.
They called out 65 pounds cold.

Before setting out I hooked up my T&P sensor, the pressure was 4 pounds less on all four tires however the cold temperature was cooler than when I pumped them up last time.

I am thinking this is normal, right?
