I don't really mean anything in particular, other than to pose the question that a higher pressure might perform better.
I really don't know, but it seems to me that a tail wag is really a soft suspension being acted on by some outside force that is out of "balance" or alignment".... i don't mean wheel balance or alignment, necessarily..... just some side forces acting on the rig.
The way I'm looking at it, soft tires are one component in a soft suspension system.
and regardless, I'd rather err on high pressure than than low.....
and from what I understand the only negative to a tire pressure set too high is a rougher ride.... so the only reason to reduce pressure would be to smooth out the ride.
I'm not a "tire engineer", "automotive engineer", or in any way an expert in these things.... but if it were me, I would set the pressures to either the sidewall max pressure or the manufacturer's pressures as posted in the door jamb, whichever is higher and carefully see what happens..... then if the ride is too rough, or whatever.... slowly drop incrementally down going no lower than the tire load tables..... But I certainly wouldn't start at the low number as I'd rather err on the high side
But as I mentioned before, it seems to me that there could very well be something wrong with your set-up causing a side loading.
Have you checked your wheel alignment?
