Why is your tube flat? Inspection is very Important.

|
|
|---|---|---|
1. Take the tire and tube off the wheelRemove the wheel by unfastening the handle holding the axle in place. Then, use a tire lever to get the tire off. Insert the lever between the tire and the rim and work it around. When the tire comes off, pull the tube out. Tips: It may be easier to remove the tube if you let all of the air out. |
2. Remove the object that punctured the tire if it’s still thereIf the object is still there, it could re-puncture the tube when you replace it, wasting all your work. Sometimes finding the object is easy, like if a nail is sticking out of the tire. Other times, glass or small rocks get trapped inside the tire, so shake the tire out to get rid of any loose objects. Tips: Gently run your fingers along the inside of the tire to free any embedded objects. If you have gloves, put them on to protect your fingers from cuts. |
3. Pump up the tube and look for the holeDo a visual check for the hole. If the hole is large, it should be easy to see. Check along the entire surface of the tube for obvious holes. Tips: Don’t stop looking when you find the first hole. If an object got inside the tire, it could leave multiple holes, so be sure to check the entire tube. |

4. Listen for air escaping if you can’t see the holeIf the hole is too small to see with a visual check, bring the tube up to your ear. Give it a light squeeze to force the air out, and listen for a “seeping” sound to hear where it escapes from. Then, use these signs to locate the hole. Tips: You still might not be able to pinpoint the hole, even if you hear the seeping sound. Use the water method to find its exact location. |
5. Dunk the tube into a filled sink to see where bubbles come up fromIf you still can’t find the hole, fill a sink with water and place the tube inside. Squeeze it so air escapes, and then check where bubbles rise up from. When you see the bubbles, you have an exact location for the hole. |
6. Rim InspectionInspect the rim strip whenever changing a tire or inner tube. Look for tears and rips, and make sure rim strip is centered over the nipple holes.In the image, the rim strip is damaged, which may cause a flat tire. NOTE: Hole on inside edge of tube indicates a problem inside the rim, such as from rim strip failure, a protruding spoke or other sharp object inside the rim. |
