| Tire Sidewall problems | |
| Tire Tread/belt problems |
Tires were manufactured on 41st week of 2018 equipped as oe tires on my 2019 kia Sedona. All 4 tires has started to developed dry rot way before the tread is even at 50 percent. I'm located in bay area (northern California) and the weather is non extreme (no snow, no triple digit heat) and the tires already show defects. Contacted kumho about issue and they gave me a runaround, instructing me to visit kia dealership to confirm the tires is dry rotted. Kia did confirm the tire is dry rotted and provided a work order stating this fact. Kumho at first deny the claim stating that it has pass the 4 year manufacturer warranty which is not true due to tire were manufactured on 41st week of 2018 as stated on the tire sidewall. After bringing the fact and evidence to bbb, kumho agreed to accept the warranty, but now are delaying the process for unknown reason. The vehicle is still equipped with the unsafe tires that I transport my family in.
Tire seze 235/60 r 18 103h - tires are original equipment on our 2019 kia Sedona. Only 16000 miles on tires. Had vehicle to dealership a few weeks before incident and tires rotated and tires were ok. Did a family trip from new jersey to florida. On the way home vehicle started shaking really bad. Hard to control vehicle. This was during the night driving at high speed on interstate I-95. I got out and looked at vehicle at rest stops in the middle of the night and saw nothing wrong. . . So I slowed down to minimum speed all the way home from north carolina to our home in cherry hill NJ. Took vehicle to dealer and was informed that there was a problem with tire. Uneven cupping around the bead of the wheel. Tried to balance. Tire was not mouting properly on rim. Rim is not bent or uneven. Tried to contact kumho and opened an incident but was told my kia dealer had to provide information, which they did, however kumho refused to help out with the cost of the new tire ($261. 67). I could have had a serious accident on the way home with a tire that only had 16000 miles on it. I am still in possession of the tire if you need to see it.
