Barum Tire Sidewall Cracks After Only 2 Months of Use

On August 27, 2025, I purchased Barum 215/65 R17 99V summer tires for my vehicle. After using the tires for approximately 2–2.5 months, I switched to my winter tires. Today, when I went to have the summer tires installed again, I had three of them installed. However, before installing the fourth tire, I noticed cracks on its sidewall. I became seriously concerned about my safety and did not feel comfortable having the tire installed.

The fact that cracks developed on the sidewall after such a short period and such limited use makes me believe there may be a manufacturing defect. I purchased the tires from Doğuş Oto for $360. As soon as I noticed the problem, I went to Doğuş Oto, but they told me they did not have this model in stock and that they would get back to me later regarding the issue.

This situation has seriously concerned me, both because of the amount I paid and because of the potential safety risk. I request that Barum inspect the cracked tire and determine whether the damage is the result of a manufacturing defect, and that the tire be replaced free of charge under warranty. I would appreciate having this issue resolved as quickly as possible.
