400 x 5 Mobility Scooter Inner Tubes: Heavy-Duty Performance and Comfort

Ensure your mobility scooter stays road-ready with our premium 400 x 5 (4.00-5) Inner Tubes. These heavy-duty tubes are the essential core of your pneumatic tyre system, providing the necessary air-filled support for a stable and comfortable ride. Specifically designed for larger mobility scooters and powerchairs, our 400 x 5 tubes are manufactured from high-grade rubber to offer maximum durability and long-term air retention.

Optimised for Larger Scooters & Powerchairs

The 400 x 5 size is common on many Class 3 (road-legal) and mid-to-large pavement scooters. These tubes are built to withstand the increased weight and speed requirements of these models:

• Superior Vibration Dampening: By maintaining the correct internal pressure, these tubes work alongside your tyres to absorb the "road chatter" from pavements, gravel, and uneven paths. This reduces physical strain on the user and protects the scooter’s electronics.

• Bent Valve for Easy Access: Because 5-inch rims are often deep and narrow, these tubes feature a bent (angled) metal valve. This smart design allows you to attach a pump nozzle quickly and easily, without having to fight for space between the wheel hub and the spokes.

• High-Elasticity Rubber: Made from thick butyl rubber, these tubes are more resistant to "pinch flats" and stretching, ensuring they conform perfectly to the inside of your 400 x 5 tyre casing.

Technical Specifications & Fitment

Confirming your size is easy—simply check the numbers printed on the sidewall of your current tyre. If it reads 400 x 5 or 4.00-5, these are the correct replacement tubes for your vehicle.
