Is a 60-series tire "low profile"? Only if you're driving KOH style or racing in Baja, or you line up 6 feet from a square edged obstacle and hit the gas, as "the best offroad driver" in that party did.
And no, I would not drive at 70mph in Baja on those tires, but climbing a forest road in Colorado, Wyoming, New Mexico (over razor sharp caliche).... I do it all the time.
Ignore the fact that Land Rovers drive on these wheels and tires all the time, if you want.
Drive appropriately for your gear and the conditions, not that hard a concept.
