I'm just glad they exist and provide a consumer type option.

Few people post about real life experiences of making this type of "improvement" to their rigs. I've done it in the past and seriously considered it for the Axis I recently had.

My recommendation is to select a LR based on real carried weight matched to at least near the mfg's minimum psi to weights charted. In other words; best results are when the published scale represents something near the actual weight. A mismatch example is a 2klb tire load on a tire with a lowest psi rating of say 75 @ 3klb+ load. Personally I experienced this combination multiple times where it presented a propensity to have less than desirable handling characteristics on some surfaces (quite unnerving to encounter).

And don't forget as we increase LR and reduce the sidewall we end up with a tire just that much closer to a wagon wheel. So while reducing tire sway and roll is great, it is also a compromise to smoothest ride.
I agree about 163% Less sidewall will mean sacrificing some ride comfort, for other consideration... Know what you're buying, and why you're buying it.
