When a nail or screw punctures a tire, it can either stay embedded in the tread or can enter and come straight out. The tire pressure leaks from the puncture hole and the tire eventually goes flat.

If you’ve got a flat tire, you may be able to save money by repairing it with a plug instead of buying a new tire. This video shows you how to make this simple, inexpensive repair in about 15 minutes. First, check to see where the puncture is. If it’s in the sidewall, do not plug the leak.
If you’re having trouble accessing the nail, you might have to take your tire off. Then, remove the nail using needle nose pliers. Use a tire plug kit to insert a rubber plug into the hole.Cut off the excess rubber sticking out using a knife or razor blade.

If you find that your tire is not inflating properly even after repairing the puncture, get a certified mechanic to inspect the tire and install your spare tire instead.
