The trailer weighs has about 2400 pounds on the
axle, ideally 1200 pounds per tire. I inflate the
tires so their capacity exceeds their load.
As well I want the sidewalls to be stiff so side motion of the trailer does not cause the wheel to begin to roll on its sidewall. (Similarly I highly inflate the tow vehicle tires for stiff sidewalls.)
As you drive down the road, though the loading may be even on the flat, roads are uneven and the loading on individual tires increase and decrease as you drive.
We're relatively protective our tires. Tire heating is related to number of revolutions per minute. We're generally drive 55 mph except on Interstates.
We're also early morning drivers. Tomorrow when we leave on a trip we'll leave early, by 8 AM, escaping the high heat of the day.
As well we have wireless temperature and pressure sensors on our tires. Though we're sometimes considered to be 'road dangerous' towing with our CRV we do a lot of monitoring of our trailer while we drive.
As we drive from climate to climate, leaving the cold northeast, we adjust our pressures always carrying a small compressor. We regularly retorque our tire lug nuts.
It all may seem silly to some but we tend towards the cautious side.
I know stiffer tires may result in a rougher ride, we have driven some extremely. long rough roads, we're not back there, we slow down on rough roads and we have latches on most cabinet doors, nothing falls out.
