Universal causes of tire and tube failure: A single puncture or small hole usually comes from a thorn, wire, or small nail. These may be repairable.

Also check the tire for thorns, etc., then remove it. Double splits are usually the result of a rim pinch. The tube has been pinched between the rim and an object on the road/trail. Increase air pressure or use wider tires. Rash causing a large, jagged hole.

These are usually not repairable. Also check for damage to the tires and rims. A cut or tear for a long time can also indicate a tire blowout. Generally, it is not repairable. Be careful when entering a tire during installation.

Inspect Before Installation: Inspect the outside of the tread for nails, pieces of glass, thorns, or other protruding objects. Visually inspect the inside of the tire casing for nails, glass, or debris. Wipe the inside of the casing with a cloth, then carefully feel the inside with your fingers. Be careful if using a tire lever.

It's very easy to use a tire lever to puncture a hole in your tube. Inspect both sides of the tire for the bead seat and for any signs of the tube coming out. Reinstall if necessary.

How do I inspect the hole in the tube? Inspect for air leaks by holding the tube near the sensitive skin of your lips or near your ear. Move the tube around its circumference. If these steps don't work, push the tube into water and watch for bubbles in the hole.
