PARTS UNLIMITED Inner Tube - Standard - 2.50-15 | 2.75-15 - TR-4 B20025

Air pressure retention is critical for consistent tire performance, and compromised tubes waste your time with constant re-inflation between sessions. PARTS UNLIMITED Inner Tubes are engineered from 100% butyl polymer—not budget blends mixed with natural rubber—which means significantly lower air leakage and stable pressure for extended periods. Whether you're running vintage dirt bikes or classic street machines, these tubes deliver the reliability that serious riders and mechanics depend on. Each tube is individually boxed with clear valve stem and size markings, eliminating guesswork during installation. The 2.50-15 and 2.75-15 TR-4 fitment covers a wide range of motorcycle and small-displacement applications, making this a practical spare to keep on hand. 100% butyl polymer Minimizes air leakage Extended pressure retention 2.50-15 | 2.75-15 sizes TR-4 valve stem Individually boxed Clear size markings MPN: 0350-0324 Bolt-in replacement
