How to Install Your KAIJA Tire Liner:
A 9-Step Beginner Master Guide
A punctured tire can ruin a fantastic ride immediately. For commuters, explorers, and recreational cyclists alike, sharp objects such as glass, thorns, and hard rocks littering the road are always lurking. That is where the KAIJA Tire Liner enters the picture, acting as a strong barrier between the sharp objects and your inner tube. The thought of putting something on your bike may frighten you, but this tutorial is intended to take away all the fear.
We're going to walk you through an easy, detailed process that transforms this job from intimidating into a simple, pleasing bit of bike maintenance. With these short steps and expert tips, you'll install your KAIJA liner flawlessly and ride with peace of mind and confidence.
Pre-Beginning: Tools & Preparation
Having tools at the ready makes things go more smoothly.
Tools Needed:
- Tire Levers (Plastic works best so you don't damage your rims)
- A bicycle pump
Optional but Helpful:
- A clean rag or paper towels
- Soapy water in a spray bottle or a small bowl
- Baby powder or talcum powder
Preparation: Work in a well-lit, clean area. Before starting, wipe down your tire and rim to remove any dirt or sharp objects that could damage the inner tube.
Step 1: Insert the KAIJA Liner Into the Outer Tire
First, remove the wheel of your bike and fully deflate the tire. Using tire levers, pry one side of the tire (the "bead") away from the rim and remove the inner tube. Then, with the outer tire taken off of the rim entirely, place it on a clean, flat surface. Remove your KAIJA liner and carefully place it inside the tire, along its natural curve. The liner should be positioned flat against the inner casing, in direct alignment from the tread area you want to cover.
Step 2: Shake or Tap Gently to Secure Proper Seating
This procedure is crucial in order to achieve efficiency as well as to prevent future issues. Hold the tire with the liner in position and shake or gently tap it against the floor. This procedure utilizes gravity to get the liner into perfect alignment inside the tire cavity. A well-aligned liner ensures balanced wheel rotation as well as prevents chafing or pinching of the inner tube rim over a period of time.
Step 3: Press the Outer Tire onto the Rim to Mount
Begin mounting the tire on the wheel rim. Start from the valve hole side. Use your thumbs to press one bead (rim edge) of the tire into the rim channel. Move slowly and gently around both sides toward the valve hole until one side of the tire is in the rim, while the other side is open for the inner tube.
Step 4: Fit the Inner Tube, Paying Attention to Proper Alignment
Proper tube installation is necessary to avoid "pinch flats." One must first inflate the new inner tube with just a small amount of air to have it round-shaped-so it won't twist or become wedged underneath the tire bead. One pro-tip is to lightly sprinkle baby powder on the inner tube, which will allow it to slide in easily and won't stick to the tire or liner.
Begin by inserting the valve stem into the rim's valve hole. Then push the rest of the inner tube into the tire, positioning it on top of the KAIJA liner and not twisted anywhere.
Step 5: Place the Rest of the Outer Tire onto the Rim
This may be the hardest part. Once more, start on the other side of the valve stem. Use the heel of your hands or thumbs to push the last tire bead over the rim's edge. When you get to the last, tight section near the valve, push the already-seated section of the tire bead down into the rim's center groove. This frees up slack to make it easier to pop on the last piece. If it's more than you can manage to do manually, you can use plastic tire levers, but take great care not to squeeze the inner tube between the lever and the rim.
Pro Tip: If your tires are stuck very tightly, adding a small amount of soapy water to the tire bead will be a lubricant and make this job a lot easier.
Step 6: Press the Outer Tire on the Other Side into the Wheel Hub
When the tire is fully seated on the rim, rotate around both sides, pinching the tire and pushing it towards the center of the rim. This prevents the inner tube from being trapped under the bead of the tire, a common cause for mysterious blowouts soon after installation.
Step 7: Inspect All Safety Lines Fully Seated
Prior to inflation, do a critical safety check. * The majority of tires have a molded "bead seat line" near the rim on the sidewall. This line should be evenly visible just above the rim's edge all the way around, on both sides of the tire. If the line falls below the rim at any point, the tire isn't seated correctly. This will result in an unstable wobble or even a blowout under pressure.
Step 8: Check Valve Positioning, Make Sure That It Is Properly Installed
Inspect the valve stem behind. It should protrude from behind the rim in a straight and perpendicular manner, not at an angle. A deformed valve indicates that the tube is tensioned at the base and can tear the rubber, causing the tire to go flat instantly. You will be able to straighten it out by shoving the valve stem up into the tire and releasing the bead, moving the tire back, and pulling it back down.
Step 9: Fill the Tire & Complete the Installation
Begin slowly adding air to the tire. Watch the bead seat lines on both sides to ensure they snap into place together. You will likely hear one or two distinct "pings" or "pops" as the tire bead snaps into its final locked position on the rim-this is good! Continue to inflate to the pressure (PSI) indicated on the sidewall of the tire.
Once in the correct pressure, give the wheel one last spin. Check for any wobble or unevenness. If it spins smoothly, your installation is complete! You can now ride with the extra puncture protection of your KAIJA Tire Liner.
