Tire Pressure Rolling?

Hello All,
Made my first pull/trip today. I checked and set the tire pressure at 105-106 PSI but noticed that the PSI read about about 120 PSI while moving. What should I expect the PSI to be? Do I set PSI lower to start? Tires say PSI @ 110 salium tires.
Thanks!

Set the PSI to the desired pressure when the tires are cold. As you drive, the PSI will increase. 120 PS is normal.

I try to keep our Sailuns at 110 psi COLD, and see pressures over 130 psi at times, especially in summer heat, and this is perfectly normal. If you start playing with pressures other than what is recommended COLD, you will just increase wear on the tires and reduce your fuel mileage. The tires are designed to handle pressure increases while rolling.

Sounds perfect. As tires heat up the air in them expands causing more pressure.

Bill, another tip on TPMS that I got from another MOC member was to set your temp to Celsius. As you travel, you don’t care so much about the actual temp as that all tires are staying close to one another. When you are set at psi and Fahrenheit, it is real easy to glance and see two numbers side by side reading 120 degrees. Usually, in the summer, my tire temp will be in the 30’s and psi in the 100’s. Easy for my brain to quickly tell pressure and temp.

I just replace the Sailuns on our 2021 Montana 3762BP. The Sailuns had less than a 1,000 miles. The tire pressure was set at 110, however when running 65 to 70 the tire pressure increased to 125 to 130 lbs. The road speed didn't matter. I just don't trust the Sailuns. I tried to get G614 Goodyears, on back order. So I went with Carlisle 235/85R16. I never use those. However, I know people who have, and they had good service out of them. I know for a fact Sailuns have had many issues. The Carlisle's require 95lbs of pressure.

Happy trails.

At 95 Lbs, I take it the Carlisles are an "F" rated tire, not a "G".
Yes there has been a few Sailun problems, we just recently lost a section of tread, but never lost pressure, we were running the 17.5 "H" rated GY G114s and had a blow out on them which caused minor damage. We run them at the max of 125 Lbs and going down the road they can go to 150 Lbs on 90 degree roads.
So no tire can be 100%, if they were tire MFRs would go out of business.

We have been very lucky we never ever had an issue with Goodyear G614's, nor the Goodyear 17" H series. We alway check air pressure prior to moving the RV. We have tire minder now, in the past we had Pressure Pro monitors, the Pressure Pro monitors was much easier to set up. The Carlisle tires we just bought was dated stamped 8/21. So they are new and made in America.

Some Goodyears tire in the past was made in China.


Happy trails.

I’d suggest using the trailer manufacturer suggested tire pressure, and bump it up 5-10 psi. This also takes vehicle weight into consideration.

Do those tires say 120 psi cold?

Where is Lobelville ? I'd be interested in buying your Sailuns if not too far away. Mine always run in the 120's and above 130 in warm weather. Normal.
I'm in Charleston SC right now.
