Mobility Scooter Inner Tube 4.10/3.50-4 - Bent Valve

A heavy-duty replacement inner tube for mobility scooters and power chairs running 4.10/3.50-4 tyres. Please note this tube is not suitable for 3.00-4 tyres.

BENEFITS & FEATURES

CORRECT FITMENT

Sized for 4.10/3.50-4 tyres on mobility scooters and power chairs. A 3.00-4 tyre needs a 3.00-4 tube instead.

BENT VALVE

Features a 90-degree bent valve, making inflation easier, especially in tight spaces where access is limited.

SCHRADER VALVE

Uses a standard Schrader valve, the same type found on car tyres, allowing easy inflation with a foot pump, air compressor, or service station air pump.

DURABLE AND RELIABLE

Made from thick rubber with reinforced seams.

EASY INSTALLATION

Simple to fit and replace, ensuring your mobility scooter or power chair is back in action quickly.

Will this inner tube fit my mobility scooter?

It fits tyres marked 4.10/3.50-4. Check the size printed on the side of your tyre before ordering.

Does this tube fit a 3.00-4 tyre?

No. Our supplier has confirmed this 4.10/3.50-4 tube is not suitable for 3.00-4 tyres — those need a 3.00-4 tube. If you're unsure, contact us with the numbers from your tyre sidewall and we'll confirm the right tube.

What is a Schrader valve?

A Schrader valve is the same type used on car tyres. This allows easy inflation using a foot pump, air compressor, or petrol station air pump.

Why does this inner tube have a bent valve?

The 90-degree bent valve makes it much easier to inflate the tyre, especially when access is restricted around the wheel.
