This was the inside of the drivers side front tire. No other tires exhibit this kind of destruction. Tires were on the car for two years, and as you can see there is still a ton of tread left. I didnt even notice that the tire was bad until it started to lose air, upon which I inspected it, saw no nail. Took it to a shop, threw it up on a lift and my jaw dropped. How can this happen? Can a bad alignment cause this or is this flat out a defective tire? Take notice of the last photo, the damage is across almost 90% of the tire.
