Enjoy peace of mind knowing that Rrskit is here to support you with product quality and a commitment to excellence.

🧩 Precautions for Use: Inflate the Rrskit tube slowly at first, keeping the valve pointed inward (towards the center of the tire). Start with a small amount of air pressure—less than 0.5 bar/8 PSI—to shape the inner tube. Always ensure that the maximum tire inflation does not exceed 5 bar/72 PSI when using rims that adhere to ISO/TC 31 standards.

😎 Be mindful of temperature fluctuations, as every increase of 3°C (5°F) will elevate tire pressure by approximately 1%. If you inflate your tires in cooler conditions and then ride in higher temperatures, such as cycling on hot asphalt exceeding 65°C (150°F), be cautious of exceeding the recommended tire pressure, which could potentially lead to tire blowouts and injuries.

🧩 In instances where pneumatic tires are stored in heat, such as inside a car, remember to deflate the inner tube to about 1 bar/15 PSI to prevent valve deformation. Your cycling experience is important to us, and following these guidelines will help ensure each adventure is safe and enjoyable.
