Is this a defective tire?

I replaced my stock runflats with Conti ExtremeContact DW tires 11,000 miles ago. Below, you can see that the left front tire (first image) is shot while the right front (second image) is fine. Inflation has been normal- in fact, when I started seeing increased wear on the outer edge, I bumped up my inflation by a few psi in hopes of arresting this advanced wear. My alignment is acceptable with a very slight pull to the left, but not distractingly so. Is this a defective tire?

Looks to me like an alignment issue or a faulty front end part. I would have the front end of the vehicle properly checked. If no faults are found I would find another alignment shop.

you def. need an alignment judging by your comment that the car slightly pulls to the left. That could be indicative of the tire not sitting flat or staying proper. Or something is wrong with the control arms/suspension on the front left side and you should have it checked out! I highly suggest getting a new tire and then getting an alignment. Make sure whomever does the alignment gives you a printout of the before and after specs. Also while you are there you can have them reduce the camber in the rear of the car to increase mileage with a minimal impact in driving dynamics!

This is not intended to sound silly, if you have a staggered set-up, when you replaced, did they put the right sizes on the right ends?

Also seems like you have some slight cupping... could be not only alignment, but as others have mentioned, a suspension problem (have them look for worn or bent pieces). Otherwise, the alignment shop needs to go and you should find someone else.

if you didnt purchase road hazard - no warranty. Road hazard is worth every penny on any high end car.

I always purchase certs from tirerack when buying new tires... Unfortunately, they will specifically exclude damage caused by bad alignment or suspension parts. Which this seem to be Unless he can get another kind of hazard warranty that would--- having it in this case wouldn't have made a difference for the OP. As this is very likely not a specific tire issue.

now, if happens to find a nail in the sidewall.. then that's a different story.

Yes, and it's not a silly question. Smaller ones in front.
