Goodyear Refused to Cover the Bubble on My 215 55 16 Tire Under Warranty

I purchased Goodyear 215/55/16 all-season 2024 model tires in November 2024, and I’ve only been using them for about 5 months. The vehicle is not used daily, nor is it driven at high speeds. Despite this, a bubble has formed on the front left tire. I take good care of my car and have never experienced such an issue with any other tire brand before. When I contacted the place where I bought the tires, they told me the manufacturer wouldn’t cover it under warranty. But these tires come with a warranty—so what exactly does the warranty cover then? I honestly don’t understand. As a long-time Goodyear user, I expected more accountability and support. I’m expecting a proper solution from Goodyear.
