During the saga of bent wheels on another thread, I've come up with yet another strange thing I've never seen before. One of the front wheels that was bent had this thing on part of the tread. The car hasn't hit anything, been in any kind of a skid or any other event. Car has just under 10k on these tires.
Two questions:
What the devil is this?
Is the tire dangerous to use?

Wow. That is crazy to have what looks like a flat spot. Just yesterday I replaced my fronts (10K miles) that were nice and even across the tire but wouldn't have survived an upcoming 3K road trip without getting too far down into the wear bars. I noticed on one of my tires I had a "groove" parallel to the main "channels" just like I see in the area of the flat spot. Personally I wouldn't drive on that unless you are just tootling around town.

I'll have to see it in person...I'm out of town right now. Seems to me I've heard on another thread about his being an example of heat spalling or delamination. Does that ring a bell with anybody?
I know how marbles look and it could be, but that looks melted. See if you can scrape any rubber off. If not I would say melted. How, I don't know. I have seen it with tire warmers that malfunctioned, but you aren't using tire warmers.
That's probably grunge from the shop floor but i agree about the tires in general. I don't like the Michelin RF's. What did you put on yours?
Continental extremecontact SPORT.
Same exact sizes. They ride better, quieter, last longer, and they're cheaper.
No more tire skipping on full turn in lock, no more following imperfections in the road and you're fighting the steering wheel, no more watching the thread at 8-10k, no more harshness. No more noise.
Definitely look into it. I made the switch twice from the RF's and been happy both times.

I was thinking along that very line. Tired of the noise and all the stuff you mentioned. Been awhile since I've driven without some sort of a spare but I think the small compressor and can of tire goop will take care of that worry. Do you carry those?
That's a flat spot, no question. You may not have realized that the tire locked under braking. Even if the antilock brakes came on it was obviously in dry conditions.

That is what they put in the Camaro trunk instead of a spare.

The last time i had a flat while driving was in 2011. In my nissan altima. One block from a gas station in which they fixed for 10 bucks.
I know most people won't be that lucky but you can't just think every time you're out driving you're going to get a flat.
Even if you got a flat every 2 years, that's a gamble i'm willing to take if i have to give up all the downsides the RF's give you, as i mentioned above.
And yes i carry tire plug kit, with a fix-a-flat, and a small air compressor. Been carrying that ever since i got my license. Never had to use it.

I'd want to check on whether the tire goop is compatible with our tire sensors, but maybe the sensors aren't all that expensive to replace. Haven't checked.
I drove my C5 for 15 years with non-run-flats, with no major problems. Not that there weren't punctures, but they all happened to leak very slowly, allowing plenty of time to get it in to a tire shop. I also carried a plug kit and a small 12-volt compressor. Had one of the leaks been faster, I think it still would have allowed me to top the tire up with air periodically, and make it to a tire shop. Never needed to use the plug kit, but one never knows.
In the C7, I still carry a compressor, even with the run-flats. It might make the difference between arriving at a tire shop with the tire still repairable, versus needing to source and pay for a new one. I very much doubt that a tire shop would just happen to have one of our tires in stock.

Why is the rim bent?
Well, you might be right on the tire. I just got the car back tonight but will not check the tire out until the weekend. Three of the wheels were bent, none severely but enough to be a pain in the ***. I think it was just a culmination of 10k miles of driving over occasional bumps and ridges, etc., on the Interstates. The car rides and feels much better with the wheels redone but I don't have a lot of long term confidence in them. Going to get new tires and wheels in a couple of months once I decide on what wheels to get.

Good advice. I already have the compressor. The goop might take out a sensor but that wouldn't be a great problem vs. destroying a tire.

WTF is with this tire?
, is no problem, will wear off or you could choose to scrape it off.
