3. Pengaturan dan Instalasi

Proper installation is crucial for optimal performance and safety. These tires are designed to be foldable for convenience, but care must be taken during unfolding and installation.

3.1 Unfolding the Tire:

Upon receiving, the tire will be in a folded state. It is normal for the tire to feel relatively soft after being opened from the folding mode. To restore its original shape for installation, gently fold or roll the tire according to the received state. Do not overexert or forcefully unfold the tire, especially the steel wire part, as this can lead to uneven installation.

3.2 Mounting the Tire:

1. Ensure the tire has regained a circular shape before attempting to mount it on the rim.
2. Carefully place one bead of the tire onto the rim.
3. Insert the inner tube (not included) into the tire, ensuring it is not twisted. Inflate the tube slightly to give it shape.
4. Work the second bead of the tire onto the rim, starting from one side and working your way around. Use tire levers if necessary, but be cautious not to pinch the inner tube.
5. Once both beads are seated, check that the tire is evenly seated around the rim.
6. Inflate the tire to the recommended pressure of 40 P.S.I. (280 KPA). Do not exceed the maximum inflation pressure.

4.2 Tire Pressure:

5. Pemeliharaan

Regular maintenance will extend the life of your YunSCM tires and ensure a safe riding experience.

• Pemeriksaan Tekanan: Check tire pressure before every ride. Under-inflation can lead to pinch flats and poor handling, while over-inflation can reduce grip and comfort.
• Pemeriksaan Ban: Periodically inspect the tire tread and sidewalls for cuts, punctures, embedded debris, or excessive wear. Remove any sharp objects carefully.
• Pembersihan: Bersihkan ban dengan sabun lembut dan air. Hindari bahan kimia keras yang dapat merusak karet.
• Penyimpanan: When not in use, store tires in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure they are clean and slightly deflated.

6. Penyelesaian masalah

This section addresses common issues you might encounter with your YunSCM bike tires.

6.1 Uneven Installation:

If the tire appears unevenly seated on the rim after inflation, it is likely due to improper unfolding or mounting of the bead. The new soft wire technology allows the tire to be folded, but the steel wire part of the outer tire cannot be completely folded without potentially leading to uneven installation if not handled correctly.

• Larutan: Deflate the tire completely. Gently manipulate the tire bead to ensure it is fully seated within the rim channel. Re-inflate slowly, checking for even seating as you go. If the issue persists, deflate again and try to gently fold or roll the tire to help it regain its original circular shape before re-mounting. Avoid forceful unfolding.

6.2 Loss of Air Pressure:

If your tire consistently loses air pressure, check for punctures in the inner tube or damage to the tire itself.

• Larutan: Remove the wheel and tire. Inspect the inner tube for punctures and repair or replace as needed. Thoroughly inspect the inside and outside of the tire for any sharp objects embedded in the tread or sidewall that may have caused the puncture.
