Could it also be that, in the case of the Exploder, the increased pressure also increased traction which would made rollover more likely in fast turns/manouvering?

Since my topic was passenger tires and passenger cars have a high resistance to rollover, I'm happy to with withdraw that first item. but let's leave it there for now, ponderous as it is.

Updated list of max sidewall Pros and cons.

Upsides of max sidewall:

1) Reduced risk of rollover resulting from loss of control from heat related tire failure.
2) Reduced failure from overheating
3) Slightly reduced stopping distances (may have to do with increased traction)
4) Reduction in hydroplaning (onset of hydroplaning happens at a higher speed)
5) Reduces slipping in snow* (depending on conditions, sometimes lower pressure is better)
6) reduces body lean in cornering, improves steering feedback (subjective)
7) Reduces fuel consumption
8) Steering effort
Downsides to max sidewall:

1) slightly harsher ride quality.
2) may increase rollover tendency in already rollover prone SUVs
3) Harder on suspension components in rough road conditions

Will add / edit this later.
