I am not a tire expert and I can't tell by looking at the tire if this one can be repaired. The slice seems rather long and deep.....but if I thought there were a chance, I would would have it inspected. We have a local place here that does this work and I had them repair a sidewall for me a few months ago. In my case, it was just a screw, but they did tell me that there are some spilts that they can fix.
