A bit surprised that we had to change out our tires in just 11,000 miles. We were told that the inside was completely bald. He did say that it is natural for the camber to go off naturally over time and because these are high-performance tires that needing to change the tires at my current rate is normal. I would like to post a poll to see where the plus owners were at when your tires needing replacement. I only want to make sure this is normal and I am not an outlier. Thank you.
