TUBE 4.00/4.50-19 110/90-19
- “Real butyl tubes” made from 100% butyl polymer, unlike other “butyl” tubes, which are blended with butyl polymer and natural rubber
- Each tube is individually boxed with a full range of sizes and valve stem types clearly marked on each box end
- 100% butyl tube minimizes natural air leakage while maintaining air pressure for a longer period of time
