I probably chipped my tire by hitting the curb when parallel parking, the tire only has about 6000 miles on it, but does it look bad enough that I should replace it?
That is a scuff at worst. As long as there's no leakage, deformity, cords showing, or bubbling of the rubber, there shouldn't be an issue with it. I would ride on it without too much worry. Just keep an eye on it for the above.
