Tire Pressure Cold

[DDC]

So it's 6F and cold and I set the tire pressure to 50lbs as recommended and we drive south for 18 hours where the temp is 78F will the tires still be at 50lbs?

No, tire pressure will increase with temp increase, however do not deflate while tire is hot. When on the road travelling I check our tires every morning while the tire is still cool before towing! Adjust as required. Best thing you can do for your tires! Safe travels.

Make SURE you add air as you go North again (remember cold tires in the morning before you leave). This is why carrying a GOOD compressor, 25 feet of hose and an air chuck is so important when Snowbirding.

I have found that "most" battery powered air compressors don't have the capacity to inflate a truck tire to 80 PSI. There is an awesome thread here on the merits of several popular brands that will fit in a trailer's compartments.
