Agree with above. A "big hole" is usually not from a poke through or pinch but from a lack of containment. A cut or slit in the tire casing, a spoke access hole in the rim that's not well covered by a good rim strip are the common causes.

There are many bikes that come from the factory with box section/double wall rims that have poor and stretchable rim strips. these strips can and do get pushed into the rim holes and/or get a slit or hole themselves. Then the tube expands into the gap and blows out like a balloon being over inflated. Think of a hernia.

If you have a box section rim and rubber rim strips replace the strip with a plastic or cloth one. Andy.
