Check the tire for thorns, etc., then remove it. Double slits are usually the result of a rim pinch. The tube was 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 generally not repairable. Also check the tire and rim for damage. A cut or tear over a long period 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.

The tire lever is very easy to puncture in your inner tube. Inspect both sides of the tire for the bead seat and any signs of the inner tube coming out. Reinstall as necessary.

How to inspect the hole on the inner tube? Inspect for air leaks by holding the inner tube near the sensitive skin of your lip or near your ear. Move the tube around its circumference. If these steps do not work, push the inner tube into water and watch for bubbles in the hole.
