Thanks for weighing in. Thats kinda what I figured. It just looks horrible. The tires have about 8/32 tread on them, so I was thinking of getting a used to replace it that's at the same wear point. Just because I'm anal.
With zero qualifications, I agree the missing chunk doesn't appear to be a concern. On the other hand, those four pieces of rubber support us at all kinds of speeds and panic stops. Pretty important part of our driving safety.
Unless you’re showing the car (and I don’t think you are), I wouldn’t bother doing anything with it. No one is inspecting your tires while you’re rolling down the street. If they are, they won’t notice that, or care either.
Most tire manufacturers and shops would probably recommend replacement (obviously). The integrity of the sidewall is compromised, and I wouldn't suggest driving it at highway speeds. There are a lot of opinions floating around on the internet, but I did stumble onto an interesting solution -- repair the aesthetic damage yourself:
That’s actually close to the curb guard not the bead which is inside sealed up against the rim.
If you very concerned, then buy another tire and relegate this one to full tire spare.
But my honest and professional opinion, superficial and should not be an issue. Oh in a previous life I was a Goodyear corporate trained store manger when I was in my mid-20s. So I know a little about tires but it’s up to you what direction to take.
