Can I drive with a nail in my tire?

Concerns & risks

You were trying to get groceries when you spotted a shiny nail head in the tread.

Pulling it can cause a fast leak.

Causes & evidence

A nail can slowly leak or worsen. Many punctures in the tread can be repaired; sidewall damage usually can't. See tire pressure and tread.

What to do

1. Leave the nail in.
2. Check pressure.
3. Get to a tire shop soon.
4. Use the spare if pressure keeps dropping.

Common mistakes: Common mistakes: pulling the nail out at the curb, which can let air rush out. Another is using a plug-only repair from the outside for everything; many professionals recommend an internal patch and plug. Punctures near the sidewall or shoulder often can't be repaired safely. Sealant cans are temporary and may affect TPMS sensors, so tell the shop if you used one. Until it's fixed, avoid high speeds and check the pressure each morning. Ask the shop to check the tire's inside surface, since damage can hide there after driving on low pressure.

Speed Man tip: Ask for a proper plug-patch repair.

Wrap-up: Leave it in. Check pressure. Repair soon.
