That's an insane level of roadforce. Michelin tires are the best in the industry for manufacturing process control (i.e. mass, stiffness, and geometric uniformity). The set of PS4S tires I just put on my M5 all balanced out with no more than 1 ounce of weight and with roadforce measurements between 0-3 lbs.
Find an experienced user of a Hunter roadforce machine, and then use the feature on the machine to measure wheel runout with the tire OFF the wheel. It's actually a pretty cool feature as it will plot the runout measurement all around the circumference of the rim.
I hate to say it, but with roadforce levels like those with PS4S, odds are very high the wheels have issues.
