【High quality】Using high elasticity and high quality butyl rubber, the thickness is increased by 40%, and the air tightness of the inner tube is increased by 200% than that of the ordinary butyl inner tube; After inflation, the tire can maintain a higher air pressure for 6-9 months, greatly reducing the inflation frequency. Good air tightness helps keep tire pressure stable, thus improving driving safety.
