Major Tire accident at 19000 miles.

Our originals made it to 29K. A rock punctured the tire like a nail while driving. I was expecting about 30k from them.

That is indeed scary; glad everyone is ok! I hope you get an answer as to what happened but won't be surprised if you don't. Sometimes, stuff just happens. They weren't high enough mileage to be down to wear bars, even if you'd never rotated the tires, so it shouldn't be anything wear-driven.

Tire was in the very good condition and rotated at 8K. Nexen Roadian GTX. My 2 possible reasons are:

• puncture and fast deflation @ highway speed. (most likely)
• some serious manufacturing defect (less likely)

I just paid for the new tire and there is no explanation or any hints given. Good to have this posted here, so if it happens to someone else, we may have a trend and a possible manufacturing issue.

I think your assessment is likely correct due to the even distribution of the shredding of the tire. It also could be a combination of too much pressure in the tire, exacerbated by heat, and potentially load. Thanks for sharing and now that we’re at 17K miles, I’m seeing wear on the tires that makes me think they won’t last another 10k miles. I won’t buy these tires again. The stopping power is atrocious (combined with the soft pads) and in rain they don’t exactly give you a sense of confident driving.

Why did you get rid of the factory tires before 20k miles? Never heard much about Nexen tires, good or bad.

Nexen Roadian is a factory tire. No changes. I got this car new in 2022.

Ahh, didn’t realize that. Thought everybody had Goodyears like mine came with.

Don't you have the SXP with Goodyear tires? That model has the best in class breaking distance in North America.

I was hydroplaning so switched to scorpion run flat at 25K.

You willingly switched to run-flat tires? To each his own but man, everybody I've ever known with those things (typically on Corvettes and BMWs) has HATED how rough they rid and has gotten ride of them quickly. What made you choose them?

Being in the tire business for over 6 years, I can guess that a puncture started near the sidewall. It ran underinflated for a long period of time, which heats up the tire. Heat is the tires worst enemy. And eventually, it gave out. It looks like the tire went near flat and you continued to ride on them, creating a lot of pressure on the sidewall until it gave out. Tires are made so well these days, it's very rare that they go defective. It happens. But it's very rare. Back in the 90s when I managed a tire shop, we had tons of defects from Dunlop, Pirelli, Uniroyal, and dozens of un named brands like Stratton, Gillette, etc. Steel cords would stick out of the tread. Tires would go out of round. Separation would happen on the tread. Tread would peel.

look them up supposed to be 70,000 mile tires.
