Not designed for road or highway use.Universal causes of tire and tube failure: A single puncture or small hole is usually a thorn, wire or small nail. These may be repairable. Check the tire as well for thorns etc. then remove. Double splits are usually the result of a pinched rim. The tube has been pinched between the rim and an object in the road/trail. Increase air pressure or use wider tires. Blowout causing a large, ragged hole. These are usually not repairable. Also check for damage to the tire and rim. A cut or tear for a long time can also indicate a tire blowout. Typically this is not repairable. Use caution when installing 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 rag and then carefully feel the inside with your fingers. Be careful if using a tire lever. The tire lever is very easy 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 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 do not work, push the inner tube into water and watch for bubbles in the hole.
