I drove over a large screw which punched a clean hole in between the tread near the middle of the tire. I had a full size spare so I just removed the tire instead of trying to patch it.
Now, what's the best permanent fix for a simple puncture? I understand that fix-a-flat is a last resort. Is some other DIY kit adequate, or do I need to take it to a shop and if so are there multiple repair options to choose from?
It is an original stock tire from a 4WD Nissan XTerra with moderate tread. It should otherwise last at least a few more years.
