Nah it's my fault. I put the rims on in September and never got an alignment, which caused inside tire wear. I guess I assumed I didn't need one since I didn't lower the car. So now I just have two more tires to replace (the fronts) and get an alignment and I'm all good. Already replaced one (had a nail and it caused a slow leak)..but I may just go on ahead and get 3 tires and a road hazard warranty on them all.
