1. Overview
This manual provides essential information for the proper installation, use, and maintenance of your SPTBMDJ 255x80 Inner Tube. This inner tube is specifically designed as a replacement part for 10x3.0 tires on electric scooters such as the Kugoo Kirin G2 Max and KUGOO Kirin G3 Pro. Adhering to these instructions will help ensure the longevity and optimal performance of your scooter's tire system.
This image displays the 255x80 inner tube, designed for electric scooters like the Kugoo Kirin G2 Max and G3 Pro. It features a standard valve stem for inflation.
2. Setup and Installation
Proper installation of the inner tube is crucial for safety and performance. It is recommended that this procedure be performed by an individual with mechanical aptitude or a professional if you are unsure.
Required Tools:
- Tire levers
- Wrench (for axle nuts, if applicable)
- Air pump with pressure gauge
- Soapy water (for bead seating)
Installation Steps:
- Prepare the Wheel: If the wheel is still on the scooter, remove it. Deflate any remaining air from the old inner tube.
- Remove Old Tire/Tube: Use tire levers to carefully pry one bead of the outer tire off the rim. Once one side is off, remove the old inner tube.
- Inspect the Tire and Rim: Thoroughly inspect the inside of the outer tire for any sharp objects (glass, thorns, etc.) that may have caused the previous puncture. Check the rim for any burrs or sharp edges that could damage the new tube.
- Pre-inflate New Tube: Lightly inflate the new 255x80 inner tube with a small amount of air (just enough to give it shape). This prevents it from pinching during installation.
- Insert New Tube: Insert the valve stem of the new inner tube through the valve hole in the rim. Ensure the tube is not twisted inside the tire.
- Seat the Tire Bead: Carefully work the second bead of the outer tire back onto the rim. Start opposite the valve stem and work your way around, using tire levers if necessary. Be extremely careful not to pinch the inner tube between the tire bead and the rim.
- Check for Pinches: Before fully inflating, push the valve stem into the rim slightly and then pull it back out. This helps ensure the tube is not stuck under the tire bead.
- Inflate the Tire: Slowly inflate the inner tube to the recommended pressure (usually found on the sidewall of the outer tire). As you inflate, check that the tire beads are seating evenly on both sides of the rim. A solution of soapy water applied to the tire beads can help them seat properly.
- Final Check: Once inflated, check for any bulges or uneven seating. Reinstall the wheel onto the scooter if it was removed.

3. Operating and Usage
While the inner tube itself does not have operational controls, its proper use is critical for the scooter's performance and safety.
Tire Pressure:
- Always maintain the tire pressure recommended by your scooter manufacturer or indicated on the outer tire sidewall.
- Under-inflation can lead to pinch flats, poor handling, and increased wear.
- Over-inflation can reduce traction, make the ride harsh, and potentially lead to blowouts.
Pre-Ride Checks:
- Before each ride, quickly check the tire pressure and visually inspect the tires for any signs of damage or foreign objects.

4. Care and Maintenance
Regular maintenance will extend the life of your inner tube and ensure safe operation.
- Pressure Checks: Check tire pressure weekly, or before every long ride, using a reliable pressure gauge. Adjust as necessary.
- Tire Inspection: Periodically remove the wheel and inspect the outer tire for cuts, cracks, or embedded debris. Remove any foreign objects carefully.
- Storage: If storing the scooter for an extended period, ensure tires are inflated to prevent flat spots. Store in a cool, dry place away from direct sunlight and ozone-producing equipment (e.g., electric motors).
- Valve Stem Care: Keep the valve stem cap on to prevent dirt and moisture from entering the valve.
5. Troubleshooting Common Issues
This section addresses common problems you might encounter with your inner tube.
| Problem | Possible Cause | Solution |
|---|---|---|
| Frequent flats/punctures | Sharp objects in tire, worn tire, low tire pressure (pinch flat) | Inspect outer tire for debris, replace worn tire, maintain correct tire pressure. |
| Tire loses air quickly | Slow leak in tube, faulty valve stem, improperly seated tire bead | Locate leak (submerge in water), replace tube if necessary, check valve stem, re-seat tire. |
| Bulge in tire sidewall | Inner tube pinched during installation, damaged outer tire casing | Deflate, re-seat tube carefully. If outer tire is damaged, replace it. |
| Difficulty inflating | Valve stem clogged, bent, or faulty; pump issue | Check valve for debris, ensure pump is working correctly. Replace tube if valve is faulty. |
