Description
A spoked wheel on a cruiser only holds air as well as the tube inside it, and the Bridgestone TR4 tube in 140B160/70-17 is sized to fill that role without stretching thin or bunching against the rim bed. Wheel builders and shops that service cruiser tires regularly know a mismatched or worn tube is the fastest way to end up chasing a leak that has nothing to do with the tire itself. The extra rubber thickness in this build resists the kind of slow seep that comes from years of small rim scuffs and spoke nipple pressure points, which is the most common way older spoked wheels lose air over time.
- Size: 140B160/70-17
- Valve: TR4
- Material: heavy duty, puncture resistant 3mm natural rubber
- Application: spoked and multi-piece wheel, tube type fitments
- Use case: cruiser and standard motorcycle rear wheel service
- Recommended: replace alongside a new tire for a clean, leak-free remount
Fitment is straightforward: this is a direct match for 140B160/70-17 tube type applications, so it drops in during a standard tire change with no modification. IPD Racing stocks this size for shops and home mechanics servicing spoked cruiser wheels, and keeping a couple on hand avoids a wasted trip when a tire swap uncovers a cracked or dry-rotted old tube.
