fyguy400,

Your assessment is spot on!

My Euro Delivery s28i M Sport does that exactly, and I have staggered tires stock which you'd think would mitigate that.

In Germany, I'd follow faster cars at 120mph, and it was all over the road.

It's like it is sucked up, and waddles left to right, and in wind it will change lanes for you.

I did top it out at 152 mph (speedo), and it was scary which I don't need to do again.

I put 12mm Burger spacers only on front, and I can get up to 130mph (speedo) before it starts that dance.

You should try 12mm spacers on front even if you have same tires all around, or 12mm all around.

I have the summer Pirelli p7's, and measure tread depth occasionally to check for out of alignment.

The wear went from 9.5/32 to about 7.5/32 all around in 8k miles, and it's very even so I don't see need for alignment.
