offroad/low traffic concern, if you drive on riprap a lot then worth considering. if mostly relatively smooth pavement then you want inflated tires for efficiencies sake.

washboards are probably a more common case, but even then it is maybe %0.0000001 of the average vehicles miles (total swag).

A psi vs/"planing speed" test for washboards might be interesting to look at too, if anyone has a washboard nearby and is bored.

I've done the pedal low tires on pavement investigation, it arent efficient.
