I also got a 10 X 12 sinigle axle trailer with a TH axle under it.

Under those conditions air it up until they are not a flat spot on the bottom of them and add another 10 pounds of air for safety sake. If you do this you will not overload it and you will change the pressure for each load.

If they truely are mobile home tires and not the improved lo-boy tires thay need the high pressure or they build heat and delaminate. They are very hard, heavy, stiff sidewalls....I know people that have trouble with them but I never have. I know they don't really like to be tandems or 3 axles making tight turns....James

90 to 100 I use them all the time. Anything under and they seperate. I had to argue with a DOT worker one day that didnt understans that the Dayton hub was actually a lowboy axle. on my Hill trailer was up to specs.

First, there should be a recommended tire pressure on the trailer somewhere.....that's assuming the tires are the correct ones for the trailer. Next, check the max pressure listed on the side of the tire. Do not exceed the maximum pressure listed on the tire regardless what the recommendation on the trailer is. If the recommendation is above the max pressure on the tire, then you've probably got the wrong tires....which is not uncommon. If that's the case fill close to the max pressure on the tire.

Seen more blown tires/tread separations from over pressure than I can count.

I do not recommend "eyeballing" it.

Reading glasses at the Dollar Stor help.
Different tires, different pressures.
Anything else is a guess.
Tire age, we all do. An underinflated trailer house tire will flip the tread in about 15 miles and those 6 plys are good for about 50 miles. Over inflated trailer house tires that are 30 years old will blow out the sidewalls.
