My 2022 Connect 241RLK has tires with a recommended pressure of 65psi. Currently she is staying in my business warehouse in Houston TX at 75Deg and not in the sun.
Tires are in the 48psi range. I am about to head to Dallas from Houston. About a 4-5 hour drive in 100+ Deg weather. Any suggestion on where I should be on psi. I am concerned about over inflating in the cool warehouse. Medium load as far as cargo, + about 200 lbs of water because I have no hook up where I am going.

I'm no tire expert but I have always been told that an underinflated tire will build more pressure than a properly inflated tire. If it was me and the tires are not old and in good shape, I would put the recommend air in them and go. If those tires are old and the TT hasn't been used in a good while I would not get in a hurry. The hot asphalt has a way of separating things. That is just my opinion so, use your best judgement or contact a tire distributor.

There should be two places to find tire pressure requirements.
First is a sticker on your trailer, I would use it first.
Second is listed on the tire as xxlbs for max load.
My truck tires say 80lbs for max load however my door sticker calls for 60lbs for max load, since that tire may be used on different vehicles, I prefer to use vehicle manufacture recommendations.
I'm sure manufacturers take ambient temps in north America into account to recommend tire pressures.

Frankly, when it's hot, inflate to max pressure. The tires will stay cooler in the long run. If you're exceptionally light, you might go to 60, but =I= wouldn't go any lower. Tire manufacturers take into account the temps and pressures a tire will see when properly inflated (or they =should=). It's not uncommon for me to see a 10 psi increase on my tires when towing in 100+ degree weather and even a bit more on the sunny side. I've seen temps at 140+. I, personally, don't tow > 65 mph. Given that my FW is placarded for D range tires, 65 psi, and I have E range tires installed, I run them at 70 psi.

Unless you know exactly how much weight your tires are carrying, then I would do exactly what Laknox recommended.
The one thing I would add, is the need to get metal valve stems, as that was the cause of my one tire failure- the rubber stem popped out.

Do you have a link to the updated tables. That one is six years old and says the numbers are being updated. Or is their web site that far behind? |

I follow the Crossroads site and there’s always discussion about inflation numbers. Heck, there’s even discussion on the truck forum I follow. As said already, running at max pressure as per tire rating is always if your running that weight. I know my tires are max at 80psi but I run 70 for my loaded weight. |
