Michelin PSS tread cracking

[GordoNx3o9]

These are the original PSS that came brand new with my M a little over 2 years ago. Currently 17k miles with 7/32 tread left. I've been lowered on Eibach and alignment was done after. Is this due to improper alignment or are these tires just bad?

The front is shown in the picture. The rears are cracked too but not as severe.

I'm going to replace the front pair soon. I know many disagrees with mixing front and rear tires, but should I get another set of PSS to replace these or go with PS4S?

Could be from not being able to rotate the tires due to staggered set up. Mine are cracking just as bad if not worse. Im also at a little under 20k.. I just went ahead and ordered 2 new fronts but its been a over a week and they still haven't arrived.

Tirerack is usally quick with their shipments, unless you ordered elsewhere.

Are you on stock suspension? I never had that issue before with any staggered setups. Maybe only happens to PSS?

I'm lowered on H&R Sport Springs. Ordered from America's Tire. Will have to follow-up with them.

What is a week/year when they were manufactured? Does it get cold in the winter where you live?

Looks like dry-rot to me. Happens to my work vehicle. It is parked out in the sun every day.
