All Four Kumho 295/35/21 Tires Cracked After One Year



I purchased Kumho 295/35/21 tires manufactured in May 2023, and all four tires have developed cracks on the inner sidewalls. It’s been barely a year since I bought them, yet they’re already showing serious structural issues.
The fact that all four tires cracked in such a short time clearly proves how poor the product quality is. I couldn’t find any direct way to file a complaint with Kumho, so I’m writing here out of frustration and disappointment.
After paying such a high price, I expected safety and durability, not this kind of defect. I’ll never buy Kumho again, and I’m waiting to see whether the company will stand behind its product and replace these faulty tires.
