I purchased my car brand new back in Dec of 2008. Not even three years later, three (3) of the four (4) tires have severe cracking where the tread meets the sidewall. The only reason the fourth tire wasn't damaged the same way is I had a nail stuck in the sidewall prior the first tire failure and had to replace it, so I can only assume it would have had the same issues. I had a slow leak and noticed the cracking on one of the tires when filling with air. The mechanic was the one who pointed out the other tire starting to crack the same way. Tonight I noticed the third tire (last original tire) also had the same cracking.
