This is precisely why.
When we're off-roading / Rock Crawling, we air down a LOT. When we're building a purpose-built machine that'll do that regularly, we use beadlocks. Not because the low-pressure has inherently less grip to the wheel (it might?), but because lower pressure means more sidewall flex. the sidewall flex is what deforms the bead, and creates a "loose" bead, which slips tires on wheels and sometimes deflates a tire altogether.
This is why I think Racerboy's idea has some distinct merit.

If there's something I do plenty of at the track, it's use the curbs. :dance:
