I'm a retired long haul trucker.(12 years owner) I'm in the habit to check tire pressure when ever I move the trailer. Always check them when the sun is not shinning on them for a period of time. normally have to add a few pounds each time. No my tires do not have leaks. tires will loose a couple pounds over a few weeks. Pressure will also change with temps, altitude, and driving speeds. A soft tire will come apart internally over time due to flex of the plys. suggest a few of you need to talk to your tire dealer about adding air. When you pay $600. for one tire you learn to take care and check air pressure.
Those of you that say you don't have to add air, are you using nitrogen??? and if so don't add compressed air to those tires, you will have problems...
