Tire size: 245/40/17 Had a blowout without any warning, causing me to hit the center console and mirror receiving cuts and bruises. Immediately was pulled to the side of the road. When I got out to see what had happened, the rubber separated from the tire, which knocked off the back end of my car, scraped the entire passenger side of the car, knocking off the door handle and unclear as to what it damaged underneath my car. I have filed a complaint with the company, dealt with a Jesse Han and contacted the CEO Darren Thomas in regards to repairing the damage done. This has gone on since June and they keep giving me the run around. There are multiple problems with Sumitomo tires and the company owes for damages

NHTSA ID 11547437 · filed Sep 29, 2023

While driving at 60mph on the a highway, without warning the passenger rear tire had a blowout. I immediately pulled off the road and when looking to see what happened, clearly seen was the rubber from the tire completely separated from the tire, causing major damage to my car. The rubber that came unattached ripped the passenger door handle off, scratched up the entire passenger side of my car, ripped off the passenger rear bumper and underneath damage as well. When taking the tire to try and get replaced, the manager of Walmart told me this was definitely a tire manufacturer defect and I should seek for the manufacturer to cover all damage due to this defect. I have filed a complaint with Sumitomo and I have gotten no response or help with this matter. In the meantime my car is not drivable due to this damage. Because they have taken no responsibility, I am filing a complaint with The Dept. Of Transportation in order to get something done.
