tire pressure

   I carry a little compressor to keep my tires filled to the correct setting [65 psi cold on D range tires].  I fill them with the compressor at home before we leave and check them again the morning after each stop while I'm also checking the lug nut torque with the torque wrench I carry in the trailer.  The whole process only takes a few minutes.  
I had an old single piston compressor that took forever to fill the tires and replaced it with this one:  https://www.amazon.com/gp/product/B077N9PXV3/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1  It runs on 12v and works really well.

	65 PSI is the standard tire pressure for load class D tires, and it is meant to be cold. Your tires will heat up as you drive, and I would be cautious about just adding 10 PSI when you get to a filling station. Fully inflated tires won't heat up as much as partially inflated tires. So (for example) if your TP is 59 PSI when you get to the filling station, that is a delta of 4 PSI. I would probably split the difference (2 PSI), and inflate them to 67 PSI when you get to the filling station. If you have a chance to stop and let your tires cool down, then I would check them again when they're cool to make sure you haven't over (or under) done it.

	I'm not a tire expert but will jump in because you say you're about to go. Cold temperatures are cold temperatures only. I don't know why, but everyone agrees that warm tire temperatures are not consistent and should not be measured. One last point, are you measuring both the trailer tires' pressure and your cars? 65 pounds is high for standard trailer tires, it sounds like your tires are rated maybe for higher speeds but its still wise to go around 60-65 mph on your trip, in my opinion. I hope your trip is enjoyable.

	I fill mine to max, for D rated 65 ft.lbs. I have an EEZ Go tire monitor, they will drift as high as 70 with speed heat.

	I'm so excited. About to set out on my first big trip from Florida to Maine via Kentucky. I'm doing some last minute checks and realized I am confused about tire pressure. The tires say 65 lbs and, sitting in my yard my gauge reads 55. But I know once I start driving they'll heat up. Is the 65 psi for cold tires? If so, how do I keep them cold while driving to fill them (or more likely adjust for the change?) Should I just go and add 10 lbs to whatever reading I get when I get there?
