Be careful when stepping into a tire during installation.Inspect Before Installation Inspect the exterior 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 case with a cloth, then feel the inside carefully with your fingers. Use caution if using a tire iron. The tire lever is very easy to punch a hole in your inner tube. Inspect both sides of the tire for the bead seat and for any signs of the tube coming out. Reinstall if 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 lips or near your ear. Move the tube around its circumference. If these steps don't work, push the inner tube into the water and watch for bubbles in the hole.
