Brand new set of Michelin pilot 4s. I don't really mess with the air pressure, I just leave it at what my indy set it at.

I drive it pretty aggressively on the street. It looks like wear/rollover from hard cornering. Why is this much rollover occurring for me on brand new tires? Is it a problem?

This happened on my last set of tires also (Continental Extreme Contact DW).

Well...what did your shop set it to?

Err try setting your tires to 36 psi all around, when cold. (not driven recently, not in the sun)

What's your COLD tire pressure? Measured first thing in the morning, not in the sun.

This might be obvious, but have you checked to ensure its not some sort of rubbing occuring at certain steering wheel positions?

What are your camber settings?

Quit off roading it

If this has happened on two separate sets of tires, I would think it's a problem with the car and not the tires. Perhaps an alignment issue and/or bent suspension component. I can't tell, but is your car stock? (not lowered, no wheel spacers, OEM wheels, etc)

The definitive way to tell how much rollover you're getting is to do the chalk marks on the sidewall at 3, 6, 9, and 12.
