basic information
【Q/A】 ○Is it okay to store the tube outdoors? →When storing the tube, please be careful to keep it out of direct sunlight. Direct sunlight can cause tiny cracks to form on the surface of the tube. Please store it in a cardboard box or wrapped in a black polyethylene bag. ○Is there any problem with reusing the tube? →There is no problem, but tubes that have been used for a long time may be stretched, so please be careful of wrinkles when setting it on the tire/wheel during reuse. ○Does Nakaigumi sell tubes? →We are contracted to produce tubes for major domestic tire manufacturers. We do not sell directly to users, so please purchase them from retailers associated with each tire manufacturer. ●For more details, please contact us.
