I purchased two Kumho tires (275/35/19 PS91 100Y, 2023 production), and both have developed cracks in the inner bead area—the section that sits on the rim, not exposed to the outside. The cracks are located in a part that isn’t even visible from the exterior.
The tire shop where I bought them examined the issue and agreed that there was a manufacturing defect, so they opened a damage report with the company. However, after keeping me waiting for nearly two months, I was told that the problem occurred because the tires were supposedly “driven under-inflated.”
This is completely inaccurate, as both the seller and my own research confirm that the cracks have nothing to do with under-inflation. The photos clearly prove this.
I’m extremely disappointed with Kumho, a brand that I can no longer recommend to anyone. They mislead customers and fail to take responsibility for defective products. I paid a substantial amount of money for these tires and was left feeling deceived and frustrated. I am requesting a full refund for the defective tires.
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 h...

However, during the seasonal tire change, I was shocked to see that all four of my summer tires wer...
In August 2023, I purchased four Kumho tires (235/50/19) online. After having them installed, my vehicle began experiencing a serious balance issue. I contacted the seller, who told me that I needed to remove the tires and send them to the importer for inspection. When I reached out to the importer...
In May 2024, I purchased four Kumho tires. At the time of purchase, I was told that the tires came with a six-month tear guarantee — they even said, “If you scrape or tear it on a curb, bring it back, and we’ll replace it.” However, in the fourth month, one of my tires tore, so I took it back to th...
I bought four Kumho summer tires in 2024, and ever since they were mounted on my car, I’ve had a persistent balance problem. I thought the rims might be the cause and changed them, but the problem remained. When I tried a different brand of tires, the vibration went away — which means these Kumho ti...
