So I just got my summer tires put back on my 2012 WRX Premium at the dealership. They came to me and told me that my winter tires were beat and asked if I wanted them disposed of. I couldn't believe that the tires were toast so I went out into the bay, and sure enough they were.
Heres my question; Why?! I feel like a set of winter tires should last more than just one season. I have 36,000 on the vehicle so far, 20,000 of which were on these tires. The tires showed cupping, and one tire had severe wear on one side. The tech couldn't recall which tires had come from which part of the car so I really have no idea where the problem lies.
About 6000 Miles ago, I was experiencing a clunk in the front end, which was resolved by replacing the front sway-bar bushings. They also did a 4 wheel alignment to help stop any other issues. About 4 thousand miles ago, I had my summer tires put on the car, but had to take them off a week later because of a massive snow storm in the northeast, and I needed to drive to CT from VT; no way i was doing that on summers. When they changed the tires around then, there was no mention of any issues with the tires at all; Same dealer and manager.
So basically my question is: How in 4000 miles, did my tires go from "ok" to completely destroyed? What should I check? The dealer told me and I quote "Because of the high performance compounds in the tire, their life expectancy is greatly reduced." The tires in question are Cooper Weather-masters, which were provided by the dealer when I bought the vehicle as a "free" addition to the sale.
I'll also note that after I got the 4 wheel alignment, I noticed my steering wheel was slightly to the right when going strait. I figured that it was the steering wheel not being aligned proper, and I didn't give much thought to it as it was only about 1/4 of an inch tops.
Any help with this would be greatly appreciated, I've done searches on this and there are just so many possible things, that I have no idea where to begin. The dealership I go to is the only one within an hour+ of here, and I'm not really sure what to do...
