I've noticed since having my TPMS system for pressure and temp that the curbside tires always run about 6-8 degrees warmer than street side. That might be why your curbside tires have ballooned out more than the street side.
Higher temps on the trailer curb side tires is likely due to the diesel exhaust. Not weight, wind or which side the sun is hitting. I use internal sensors on my trailer so they are less sensitive to sun or wind effects, yet these internal sensors always show the curb side tires are hotter than the street side tires. Also, there has been at least one case of plastic trim on a fiver being melted by diesel exhaust temps during regen, so I frequently check my fiver for similar damage.
