I have Continental ExtremeContact DWS tires on the tC, they have approx. 13,000 miles on them. I rotated them the first time at about 6,000 miles, and just now (about 7,500 more miles give or take). When I was rotating them (front to rear on same side), the right side tires were about the same, probably 6/32 or so, the "S" on the tires was just wearing away. On the left side however, the front tire has very little tread (you can see Lincoln's head on the penny = 2/32 I think?) while the left rear has more tread than the other tires. So that means a tire rated for 40 or 50,000 miles only lasted about 13 - 14,000.
Now for the really concerning part. When I had the car inspected in March, 4,000 miles ago, the tire had 8/32 of tread on it. An alignment was performed back in January so while it's possible, it seems unlikely that the alignment could be that bad after a few months, especially because this extreme wear seems like it started sometime after it was inspected.
What do you guys think could be the problem?
How should I continue from here, as far as taking the car in and showing Walmart (where I bought the tires)?
(Btw, sorry for the lengthy post, and sorry if it's in the wrong place)
Thanks in advance!
