That's a good size or has it still got it's head on it ?
Shouldn't be problem to fix, most likely a M/plug will do the job. Try to avoid them using a push in plugusing a mushroom will mean the tyre will have to come off the rim for it to be fitted, but still shouldn't take more than 30mins to do the whole job.
Picked up a M10 bolt a few years ago in my rear tyre that was able to be repaired (but it was valcanised though).
