Parts Unlimited Inner Tube – 170/80-15, 90° Center Metal PV Valve

Parts Unlimited Standard Inner Tube – 170/80-15

When it comes to holding air and holding up to the road, Parts Unlimited's 100% butyl inner tubes set the standard. Unlike blended tubes that cut butyl with natural rubber, these are made from pure butyl polymer — meaning slower natural air leakage, longer-lasting pressure retention, and a more consistent ride from the first mile to the last. Sized at 170/80-15 with a 90° center-mount metal PV valve stem, this tube is a direct-fit replacement for a wide range of street and dual-sport applications.
