The only way to tell if the tire is good is to take off the tire. If you drove on the tire while flat, you'll see a wear line on the inside of the sidewall. You'll know immediately when you get the tire half off because there will be rubber shavings on the inside. If you do have wear on the inside then the tire should be replaced for track use. You might be okay for regular street driving.
Otherwise, the tire is fine. From looking at the pics, I think you'll be OK.
