2.2 diegimo žingsniai
- Remove the old tyre: Deflate the old tyre completely. Use tyre levers to carefully pry one bead of the old tyre off the rim. Once one side is off, remove the inner tube. Then, remove the second bead and the old tyre from the rim.
- Inspect the rim: Check the rim tape for damage and ensure there are no sharp edges or spokes protruding that could puncture the new inner tube.
- Install one bead of the new tyre: Place one bead of the Schwalbe Road Cruiser Plus tyre onto the rim. Ensure the tyre's rotation direction (if indicated) matches the direction of travel.
- Insert the inner tube: Lightly inflate the inner tube so it holds its shape. Insert the valve through the valve hole in the rim. Carefully tuck the inner tube inside the tyre, ensuring it is not twisted.
- Install the second bead: Starting opposite the valve, work the second bead of the tyre onto the rim using your thumbs. For the last section, you may need to use tyre levers, being careful not to pinch the inner tube.
- Check seating: Before fully inflating, ensure the tyre beads are evenly seated on both sides of the rim. You can do this by pushing the tyre bead towards the rim center and checking for even spacing.
- Inflate the tyre: Inflate the tyre gradually, checking that the beads remain seated. Inflate to the recommended pressure range indicated on the tyre sidewall. Do not exceed the maximum pressure.

3. Naudojimo instrukcijos
The Schwalbe Road Cruiser Plus PunctureGuard tyre is designed for urban and touring use, offering a balance of comfort, grip, and puncture protection.
3.1 Tyre Pressure
- Always maintain the correct tyre pressure as indicated on the tyre sidewall. This is typically expressed in PSI (pounds per square inch) or Bar.
- Under-inflation can lead to increased rolling resistance, premature wear, and a higher risk of pinch flats.
- Over-inflation can reduce grip, decrease comfort, and potentially lead to tyre damage.
- Check tyre pressure regularly, ideally before every ride or at least once a week.
3.2 Važiavimo sąlygos

4. Priežiūra
Regular maintenance extends the life of your tyres and ensures safe riding.
4.1 Valymas
- Clean your tyres with water and a mild soap solution. Avoid harsh chemicals or solvents, as these can damage the rubber.
- Remove any embedded debris (glass, thorns, small stones) from the tread to prevent future punctures.
4.2 Inspection for Wear and Damage
- Regularly inspect the tyre for cuts, cracks, bulges, or excessive wear.
- Look for wear indicators on the tread (if present). When these are no longer visible, the tyre should be replaced.
- Check the sidewalls for signs of cracking or degradation.
4.3 PunctureGuard Technology
The PunctureGuard layer provides a high level of puncture protection. While it significantly reduces the risk of punctures, it does not make the tyre completely puncture-proof. Regular inspection and maintenance are still recommended.
