Before the warranty runs out, I'll be sure to take it to another dealer and see what they have to say. Hmm, if a warranty repair (assuming they say it is covered) is why my tires are cupped (both the dealer and my tire dealer told me that was caused by the suspension issue), should my vehicle warranty cover the replacement since the tire damage was caused by the suspension issue? I know my tire warranty doesn't cover it because it isn't a defect in the tires but due to issues with the suspension (which is a shame since they are newish tires, about 15K miles, and pretty good Yokohamas).
