I've had this happen 2x before with brand new michelin's.

Try swapping the front tires around from side to side, the direction that they pull should swap. I ended up getting the tires covered under warranty from a local store.

 

I had this problem and it seemed to be different air preassure in the rear tires. Once I get them to the same PSI it goes away.

My problem is one of the rear tires (they are brand spanking new!) keeps losing air preassure! Do I have a bad rim? I have never hit anything or hit any big potholes, I don't track the car either. Only drive on the weekends.

 

sounds like a tie rod, although that is premature wear, exact same symptom i had.

 

I say check the bushings/bearings in the rear to find your problem

 

I had the same problem, ended up being a slow leak in my tire.
