Handle the leak first without turning a small puncture into more damage

  1. 01
    Leave the object in place until the tire can be evaluated

    Pulling a nail or screw can make the leak faster and removes a useful reference for where the puncture entered. Photograph the location if you can do so safely.

  2. 02
    Check pressure and how quickly it is falling

    A tire that is visibly low, rapidly losing pressure, vibrating, or showing sidewall damage should not be treated like a normal drive-to-the-shop situation.

  3. 03
    Avoid driving on a severely underinflated tire

    Running low can damage the sidewall and inner structure even when the original puncture was small. Use the spare or roadside help if the tire cannot hold a safe pressure.

  4. 04
    Have the tire removed from the wheel

    A proper decision requires seeing the inner liner and checking for heat, abrasion, cords, previous repairs, and hidden damage that cannot be judged from the outside.

The same nail can lead to different outcomes depending on where it entered

Center tread area
A small puncture that falls within the tire maker’s repair zone and size limits

This is the area most likely to be repairable, but only after internal inspection confirms there is no additional damage.

Shoulder near the tread edge
Professional evaluation rather than an assumed repair

The shoulder flexes and transitions into the sidewall. Many repair standards and tire makers exclude this area from normal puncture repair.

Sidewall
Replacement in most ordinary puncture situations

The sidewall flexes heavily in use, and a plug or patch in this area is generally not treated like a repair in the central tread.

Ask the tire shop to check more than the hole itself

  • Whether the puncture is inside the repairable tread area specified for that tire
  • The puncture diameter and angle
  • Signs the tire was driven while severely underinflated
  • Damage to the inner liner, cords, bead, or sidewall
  • Any previous repairs close to the new puncture
  • Remaining tread depth and uneven wear
  • Whether the tire has special run-flat or manufacturer-specific repair restrictions

Stop and get help

A temporary string plug is not a reason to ignore a safety inspection

Do not treat an emergency plug, sealant, or inflator kit as proof that the tire is permanently safe. Follow the product and vehicle instructions, limit driving as directed, and have the tire professionally inspected before returning to normal highway use.
