Tire Inner Tube

Product: Tire with Inner Tube – CST Brand

1. Brand: CST (Cheng Shin Tire)

CST is a well-known brand in the tire industry, particularly for bicycles, scooters, carts, and other small vehicles. It is known for offering quality, durable, and reliable products. The tire you mention is part of their inner tube range for light vehicles.

2. Tire Type: Inner Tube

This tire is an inner tube, which means it includes an internal air-filled tube, located inside the outer casing of the tire (the “rubber”). This type of tire is commonly used in bicycles, scooters, wheelchairs, and other light equipment.

Inner tubes offer several advantages, such as:

• Increased comfort : The air contained in the tube acts as a shock absorber, providing a smoother ride and absorbing impacts.
• Repairability : In the event of a puncture, it is often easier to repair an inner tube than to buy a complete tire.
• Flexibility : You can adjust the pressure of the inner tube to optimize performance depending on the type of surface.

3. Dimensions : 8 1/2 x 2

The dimensions 8 1/2 x 2 refer to the tire size. It is a relatively small tire, commonly used for light vehicles or devices such as:

• Compact bicycles
• Scooters
• Hand carts
• Electric scooters
• Wheelchairs (in some cases)

These dimensions are generally broken down as follows:

• 8 1/2 : The tire diameter, measured in inches, or about 21.5 cm. This makes this tire suitable for small vehicles or applications requiring a compact wheel size.
• 2 : The tire width, also measured in inches, or about 5 cm. A width of 2 inches is ideal for a good balance between stability and maneuverability.

4. Maximum Load : 75 kg (165 lbs)

The maximum load indicated for this tire is 75 kg (165 pounds). This means that the tire can support a combined load (vehicle + user) of up to 75 kg without compromising the safety or performance of the tire.

Why it matters :

• If you use this tire for a bicycle or scooter, it is important not to exceed this load to avoid damaging the tire and ensure safe riding.
• Overloading can cause tire overheating, premature wear, and loss of performance.

5. Maximum Pressure : 340 kPa (50 psi)

The maximum inflation pressure for this tire is 340 kPa (50 psi), which is the maximum recommended pressure to ensure optimal performance. This means:

• 340 kPa (kilopascals) is equivalent to about 50 psi (pounds per square inch). This pressure is typical for small tires that require good rigidity without being too stiff, to ensure a comfortable ride.
• It is important not to exceed this pressure, as too high a pressure can lead to premature tire degradation or a puncture, while too low a pressure can affect vehicle stability.

6. Operating Temperature : Cold (Cold)

The mention “cold” indicates that the tire must be inflated and used at ambient temperature, before it reaches high temperatures due to use. Hot temperatures can cause an increase in the tire’s internal pressure, which can be dangerous if the initial inflation pressure was too high.

Usage and maintenance tips :

• Inflation : Use a suitable pump to ensure that the tire pressure remains within the recommended range (up to 340 kPa / 50 psi). Check the pressure regularly to ensure safe riding.
• Repair : In the event of a puncture, it is possible to repair the inner tube using special patches or by simply replacing the tube if necessary.
• Inspection : Regularly inspect the condition of the tire to detect any wear or visible damage (cracks, punctures) to ensure its durability.
