I guess that's one theory, but 99 out of 100 tech articles don't agree with your skinny rim idea.Probably OK at 10mph going over a rock, but once your up to 30-35mph and have to turn through a curve watch out.
Ive never lost a bead. Friends with wide rims have.
The street "stance" bros with their wicked wide rim and narrow tire that have to strech the tire to seat the bead, they have to run high pressures to keep the tire on.
As to articles, theyre written by mags or other journo companies, right? They have to worry about lawsuits if they deviate from mfr recommendations.
Not saying to run a 5" wide rim. The stock 7" is .5inch below most mfr reccomended rim width. Those rim widths are reccomended to maintain a flat tread at higher pressures and higher loads.
If you monitor treadwear, temps, abnormal wear, ... these will inform decisions.
Also, i dont care what rim size you run... driving at 35mph on 15psi is begging for a blowout.
Lower psi means more sidewall action, means more tire heat, means shorter tire life. If youre driving slowly (which is why youve aired down) you generate heat at a slower rate, allowing the tire to dissipate that heat.
If you can run 35, you dont need to drop below 25
