Next time out. Take a temp gun with you. Measure the temp at the outside, middle, and inside of the tread. Take notes. If center is hotter, lower pressure. If both outside and inside temps are higher then the center. Increase pressure. Also you can use this method to adjust your alignment. MaysEffect can explain it better then me. He's long winded.
That tire looks like it was chucking. And if that's the case. You may have over-heated it.
