The rubber content is 45% more than that of ordinary inner tubes, and the sidewall thickness is increased. When facing sharp objects, ordinary inner tubes may be easily punctured, while our inner tube, with its thicker sidewalls and high rubber content, can effectively resist the risk of puncture and reduce damage. Meanwhile, the high-quality butyl rubber enables the inner tube to remain airtight for up to six months, saving you the trouble of frequent inflations
TR13 straight - type valve stem: The valve stem is coated with rubber, which effectively improves the valve seat seal and prevents sand, dust, etc. from entering the inner tube and tire. It can withstand extreme temperatures, and its performance is not affected by either severe cold or intense heat. At the same time, it is corrosion - resistant and less likely to be damaged in complex environments, thus having a longer service life
Installation tips: When installing, first inflate the inner tube slightly and place it into the outer tire that has been cleaned in advance. Then continue to inflate until it closely adheres to the outer tire wall. Before use, be sure to check if the inner tube is leaking. If there is a leak, please leave a message and provide relevant proof pictures so that we can solve the problem for you more effectively
