Not All Tires Need Repairs
Sometimes, an injured tire can't be repaired and instead needs to be replaced. This usually happens if
the puncture is more than a quarter-inch to three-eighths of an inch in diameter (about 6mm to 10mm).
Major damage from accidents and other road scenarios also qualify a tire for a complete replacement.
Some tire manufacturers also have specific standards that prevent certain types of tires from getting
repaired.
