This is a motorcycle inner tube made by IRC, sized 170/80-15, using the PV-78 valve standard (a metal 90° valve stem)
The tube is made from a blend of natural rubber and butyl for flexibility, durability, and air retention.
It is used inside a 170/80-15 tire (i.e., rim diameter 15 inches) and provides an internal pressure seal between the inner and outer tire.
Many listings note “highest quality Japanese tubes that meet or exceed OEM quality and performance”
Valve stem: PV-78 metal, which is a tall, 90° bent stem design.
It’s marketed as “standard duty” rather than “heavy duty,” but more robust than very thin tubes.
