RUTU's 12.5 x 2.75 inner tube and matching heavy-duty tire is a complete replacement kit designed to fit most 12" (12 1/2 x 2 3/4) kid's dirt bikes, pocket bikes, scooters and mobility wheels.

This RUTU tire-and-tube set combines thicker butyl rubber, reinforced carcass layers and an aggressive square-tread pattern to deliver longer-lasting inflation, better puncture resilience and improved traction on uneven or wet surfaces. The package includes one 12.5x2.75 inner tube, one 12.5x2.75 dirt bike tire and two plastic dust caps, plus a one-year replacement warranty.

What wheel and vehicle types will this 12.5 x 2.75 set fit?

This kit is sized for 12" wheels listed as 12.5 x 2.75 or 12 1/2 x 2 3/4. It’s compatible with many small-engine bikes and scooters used by kids as well as some mobility scooters and electric/gas scooters that accept the same diameter.

• Fits most 49cc, 50cc and 70cc kid’s dirt bikes and pocket bikes
• Works on many mobility scooters and small electric/gas scooters
• Check your rim dimensions and existing tire sidewall size to confirm fit

How does the inner tube keep air longer and resist flats?

The inner tube uses higher-content butyl rubber and an improved construction that increases elasticity and sealing. A bent TR87 pure-copper valve and tight bead construction help minimize slow leaks and simplify inflation.

• 45% more rubber content for better puncture and abrasion resistance
• 4.8× more stretch for easier seating and fewer pinches during installation
• TR87 bent copper valve with strong seal; holds air up to about 180 days

What traction and durability features does the tire offer?

The tire features deep, square-pattern tread blocks and multiple reinforcement layers to improve grip on mud, loose soil and slippery terrain, while protecting the carcass from impacts and wear.

• Deep square tread pattern for enhanced bite and water shedding
• Four nylon-reinforced carcass plies for puncture and tear resistance
• Upgraded 9-strand bead chafer for secure rim seating and durability

• One 12.5x2.75 dirt bike tire and one matching butyl inner tube
