200 × 50 Pneumatic Inner Tube - Single

Replacement 200 × 50 inner tube for compatible electric skateboard, mountainboard, scooter, cart, and small electric-vehicle pneumatic tire systems.

This tube is designed for use inside compatible 200 × 50 tires and wheel rims. It allows builders to replace a punctured, pinched, leaking, or worn tube without replacing the complete tire.

Sold individually for convenient maintenance, repairs, and custom vehicle builds.

Key Features

• Sized for compatible 200 × 50 pneumatic tires
• Suitable for 8-inch × 2-inch tire applications
• Replaceable tube for punctures, leaks, and damaged valve stems
• Useful for electric skateboards and DIY electric-vehicle projects
• Compatible with appropriately sized wheel rims and tires
• Sold individually

Common Applications

This inner tube may be used with compatible:

• Electric skateboards
• Mountainboards
• Electric scooters
• Drift carts
• Small electric carts
• DIY modular electric vehicles
• Other wheel systems using 200 × 50 pneumatic tires

Compatibility depends on the tire, rim, valve-stem configuration, and available valve clearance.

Specifications

• Tube size: 200 × 50
• Nominal size: 8 × 2 inches
• Tube type: Pneumatic inner tube
• Material: Rubber
• Quantity: One inner tube
• Tire: Sold separately
• Wheel rim: Sold separately

Add the exact valve-stem specification once confirmed:

• Straight or angled valve stem
• Valve angle
• Valve type
• Valve-stem length

That detail is important because the wrong valve orientation may be difficult or impossible to access after the wheel is assembled.

What’s Included

• One 200 × 50 pneumatic inner tube

Tire, wheel rim, hub, bearings, and mounting hardware are not included.

Compatibility

Before ordering, confirm:

• Your tire is marked 200 × 50 or 8 × 2
• The wheel rim accepts the tube size
• The valve-stem type and angle match your wheel
• There is enough clearance to inflate the tube
• The tire and rim are free from damage or sharp edges

Do not rely only on the approximate outside diameter of the tire.

Installation

For best results:

1. Inspect the tire and rim for debris, sharp edges, or damage.
2. Add a small amount of air so the tube holds its shape.
3. Position the tube evenly inside the tire.
4. Insert the valve stem through the rim opening.
5. Assemble the wheel without pinching the tube.
6. Confirm the tire bead is evenly seated.
7. Inflate gradually while checking the tire and valve position.
8. Do not exceed the pressure marked on the tire.

A pinched or twisted tube may fail immediately or lose air after installation.

Troubleshooting Repeat Flats

Before installing a replacement tube, inspect the entire tire and rim.

Repeated punctures may be caused by:

• Debris remaining inside the tire
• Sharp or damaged rim edges
• A pinched tube
• Incorrect tire pressure
• Tire-bead installation problems
• Damaged valve-stem openings
• An incompatible tube or rim
• Riding with insufficient air pressure

Replacing the tube without correcting the underlying cause may result in another failure.

Important Safety Information

Do not use a tube that is damaged, twisted, improperly seated, or leaking.

Check tire pressure before riding. Underinflation can allow the tube to pinch or shift, while excessive pressure may damage the tire, tube, or wheel assembly.

Inspect the complete wheel assembly before every ride.
