4.00-4 (400 x 4) Mobility Scooter Inner Tubes: Heavy-Duty Support for Large Wheels
Restore the ride quality of your mobility vehicle with our premium 4.00-4 (400 x 4) Inner Tubes. Engineered for the demanding requirements of larger powerchairs and heavy-duty mobility scooters, these tubes provide the high-capacity air cushion needed to support significant weight while maintaining a smooth, vibration-free roll. Whether you're navigating urban pavements or light off-road paths, these tubes ensure your tyres perform at their absolute peak.
Reliability Meets Effortless Maintenance
Choosing a high-quality inner tube is the most cost-effective way to prevent flat tyres and protect your scooter's motor:
-
Versatile Fitment: These tubes are designed for maximum compatibility and can be used in tyres marked 4.00-4, 400 x 4, or even the slightly larger 410/350 x 4 profiles, making them a versatile essential for your maintenance kit.
-
Reinforced Butyl Rubber: Our 400 x 4 tubes are crafted from thickened butyl rubber, providing superior resistance to "pinch flats" and air seepage. This high-density material ensures your tyres stay at the correct pressure for longer, improving battery range and motor efficiency.
-
Precision Bent Valve: Large 4-inch rims can be deep and difficult to navigate. These tubes feature a 90-degree bent metal valve, allowing you to attach any standard pump easily without the valve stem being obstructed by the wheel hub or motor housing.
-
Maximum Shock Absorption: Designed to hold higher volumes of air, these tubes act as a secondary suspension system. They effectively dampen the impact from kerbs, potholes, and tactile paving, offering a significantly more comfortable experience for the user.
Technical Specifications & Fitment
The 4.00-4 is a standard size for heavy-duty drive wheels. Before ordering, please check the sidewall of your existing tyre to confirm this exact size or its compatible variants.
