Small tire punctures (from nails, screws, or small rocks) are common—but if left unaddressed, they can lead to flat tires or even blowouts. Catching and fixing them early saves you money and prevents further tire damage.
First, know the signs of a small puncture. A slow air leak is the biggest clue—if you have to add air to a tire every few weeks, it’s likely punctured. You might also notice slight vibrations while driving, or the tire feels softer than usual.
To find the puncture, inflate the tire fully, then spray a mixture of soap and water on the tread and sidewall. Bubbles will form where air is leaking—mark the spot with chalk.
If the puncture is in the tread (not the sidewall) and less than 1/4 inch wide, it can usually be fixed with a tire plug or patch kit. These kits are affordable and easy to use at home. But if the puncture is on the sidewall, don’t try to fix it—sidewall damage is too risky, and the tire needs to be replaced.
After fixing the puncture, check the tire pressure again and monitor it for a few days to ensure the leak is sealed. If the leak persists, take the tire to a professional—there might be additional damage you missed.
