Sometimes the real culprit isn’t the nail. It’s a crusty old valve stem. A valve stem replacement can cost $15 to $30, while a simple plug is often under $20. Your tire is fine, but its little rubber mouth is broken.
It’s like paying for a dental filling just to find out you need a new toothbrush.
The “inside vs. outside” debate is pricey.
Many shops insist on an internal patch. That means taking the tire completely off the rim. It’s safer, but it adds labor. A plug from the outside is cheaper, but some shops won’t do it because of liability.
So you’re paying for safety—or for a mechanic’s paranoia. Either way, your wallet feels the pinch.
