Premium replacement for rough rides

Keep your dirt bike or electric scooter cruising with YeYouC heavy-duty inner tubes designed for 12.5x2.75 tires. The thickened construction adds durability for challenging surfaces, while the straight valve stem simplifies inflation. These tubes are meant to support your rides on bumpy trails and everyday use, offering a steadier feel without promising guaranteed results.

Why this tube stands out

Built to handle the demands of off-road and urban riding, these tubes combine durability with practical features. The rubber and wall design emphasize resilience, shock absorption, and long-term performance. The result is a smoother experience on uneven ground, with a focus on reliability and consistent pressure over time.

  • Heavy-duty butyl rubber is used to deliver a more robust replacement than standard tubes
  • Thickened walls provide better vibration dampening on rough terrain
  • AV Straight Valve Stem paired with reinforced walls helps maintain air pressure
  • Precision vulcanization minimizes seam leaks for reliable sealing
  • Contains two inner tubes and two valve caps for a ready-to-install kit

Fit and compatibility at a glance

  • Size: 12.5 x 2.75 inches (outer diameter 12 to 12.5, width 2.75, rim diameter 8.5)
  • Wide compatibility with many popular dirt bikes and scooters that use the same tire size
  • Please confirm your current tube size before replacement to ensure proper fit

Real-world use often benefits from a tube that can dampen harsh chatter and maintain a steady air pressure on uneven surfaces. The package includes two tubes and two valve caps, and YeYouC offers a 100% refund or free replacement if you encounter any issues after purchase. For best results, perform a water test to verify there are no leaks before full installation.

What you get and how to install

  • Two 12.5 x 2.75 inner tubes
  • Two valve caps
  • Tip: submerge the tubes in water to check for bubbles before installing to confirm air-tight integrity
