I didn't get any wallow until I had about 6000 miles on the rear tire. By then the center of the tread had sort of squared off. Could it be the wallow is caused by reduced tire patch in hard cornering? A bit of sidewall squirm? A little tire slide? Everyone agrees the wallow comes at higher speeds, when centrifugal forces would be much higher to the outside of a curve. This would load up the tire's contact patch causing some flexing of the side wall and the tread. I would call this a wallow (also?).
I get some wallow running at high speeds in the Virgin River Gorge, at 75-80 in curves posted for 60-65mph. It is most prevalent when the pavement heaves a bit. On the back roads where the curves are tighter, I get little or no wallow unless,again, the pavement heaves.
I just live with it. I'm not threatened.
