The 65 profile gives almost 10 mm more ground clearance. The down-side is that the 65 profile often is available only for higher load index with stiffer side walls.

Good point. However, I wonder if by going up in profile, hence making a bigger balloon, perhaps one should also go up a category in load index to get an equivalent amount of “squishiness” ?
Don’t really know, maybe it doesn’t work like that.
