Im sure driving out of the woods to get a tire fixed is ok. But the last time I had a flat , I put the spare on and drove home 180 miles. That was with stock size tires all around. If you rip a sidewall apart on the trail then there is no fixing the tire. there might not be a tire shop nearby or one that is open. You may have to travel back home on a spare that is not the same size as the others, and that can very easily be of some distance.
