Air Pressure

Thanks JIMNLIN.
That web site has good info.

This from Tireman9 rvtiresafety.com blog. Roger is a tire engineer and has some very good tire info regarding tires on our trailers. Check him out. http://www.rvtiresafety.com/search/label/Cold%20Inflation

BOTTOM LINE
Tire & wheel manufacturers account for a normal pressure increase as outlined above when they design tires & wheels, so you should not be concerned unless you are seeing a large increase in pressure. If you do see a pressure increase like 25% you need to find out why. Remember you should not be bleeding down your tires when they are hot.

OK, thanks all for your answers. 3 yes, 3 no & 1 I'm not sure.
I always check the pressure before moving, as it is flashing on the dashboard.
I was just wondering how many folks reduce the air pressure, ie let air out because of the rise in ambient air temp.
Last year when I left, I had 80psi @ 30 degrees, the second morning when leaving Tampa the temp was 65 degrees the TST said 2 tires @ 83psi & 2 tires @ 84psi. I did not let air out and based on the 3 no's, probably won't do it this year. If I have a blow out, you yes's can holler out the window as you drive by & say "I told you to adjust it"...........

I always make checking tire pressure my pre hookup check. It just does not take that long for safety.

Check your tires and set them to the recommended pressure each day before travel. That is the instructions from EVERY tire manufacturer.
Good luck / Skip

No, and I've been leaving from Pittsburgh since 2003.

If you check and adjust the air pressure every morning as recommended it is not an issue.

Another question I saw posted some time back in a similar vein, "Do you adjust the air pressure every time you change elevation?" Same answer, check and adjust every morning before travel.

I would only worry about it if I were close to my max pressure on the wheel itself. For example, on my rears, I run them at 115# and the wheels are rated for 120#. It is not clear what temperature differential it would take when the tires are cold to result in going over the 120#.

Dont do it.

No. Air pressure is set when the tire is cold. If you change from -40 to +80 then yes, adjust them. But if your going from 45-50 to 70 dont worry about it.
