If my assumption is correct, I would have thought that non-run flats would take you back to square one in that they have more flexible sidewalls.
I'd appreciate any further enlightenment - thanks,

My experience on rutted roads has been that the lower the profile and wider the tyre the more wandering. The sidewall doesn't have much flexing potential and that increases the wandering tendency. The F10 on 225/55R17s is much better than my E60 was on 245/45R17s
