This replacement inner tube set is designed for parents and caregivers maintaining strollers, prams, pushchairs, and buggies that utilize pneumatic tires. The primary benefit is the inclusion of a bent Schrader valve, which significantly simplifies the inflation process in tight wheel spaces compared to standard straight valves. A key caveat to note is that these tubes are specific to the 255-series sizing, so verify your existing tire sidewall markings before purchase to ensure compatibility.

Yes, this inner tube is specifically designed to be compatible with 255x50, 255x55, 255x60, and 39-177 4 tire sizes.
The bent valve is designed to provide easier access for pump nozzles, especially in strollers where the space between the wheel hub and the frame is limited.
Yes, because these tubes use the standard Schrader (car type) valve, they are compatible with almost all standard vehicle and bicycle tire pumps.
This set includes two high-quality inner tubes.
These are intended for strollers with pneumatic tires matching the 255-series dimensions. Please check your current tire sidewall for size specifications before ordering.
Check if the tube was pinched between the tire bead and the rim during installation, or ensure the valve core is fully tightened.
Deflate the tube slightly and massage the tire around the circumference to ensure the tube is seated evenly within the casing.
To install, first ensure the stroller is secured on a stable surface. Deflate the old tube completely, remove the wheel from the frame, and use tire levers to carefully pry the tire bead from the rim. Once the old tube is removed, inspect the inside of the tire casing for sharp debris like thorns or glass shards that may have caused the previous puncture. Lightly inflate the new tube with just enough air to give it shape, insert it into the tire, and seat the tire bead back onto the rim. Ensure the valve stem protrudes straight through the rim hole before final inflation. Check your tire sidewall to confirm it lists one of the compatible sizes: 255x50, 255x55, 255x60, or 39-177 4.
