CST High Pressure Inner Tube with Standard SCHRADER Valve

Wheelchair Tire Inner Tubes

Most wheelchairs use high pressure inner tubes. To see if your wheelchair needs high pressure tubes, take a look at the sidewall of your tires. If the psi required is above 40psi, we recommend you use these CST High Pressure tubes.

High Pressure SCHRADER Valve Inner Tube by CST Buyer’s Guide

The High Pressure SCHRADER Valve Inner Tube by CST is engineered to deliver reliable air retention and puncture resistance for active manual wheelchairs, sports chairs, and high-performance bicycles. Designed to accommodate the demands of high-PSI pneumatic tires, this durable butyl rubber tube ensures peak rolling efficiency, reduced drag, and a smooth, comfortable ride across paved surfaces and varied terrain.

High-Pressure Pneumatic Capability

Unlike standard tubes prone to pinch flats at lower pressures, this CST inner tube is constructed to withstand the rigors of high-pressure seating (often 100+ PSI for active wheelchair tires). Maintaining high inflation levels decreases rolling resistance, making propulsion easier and reducing fatigue for active wheelchair users.

Durable Butyl Rubber Construction

Manufactured from high-quality, premium butyl rubber, the tube offers excellent air retention and resistance to standard punctures, abrasions, and daily wear. Its robust construction ensures long-lasting integrity, minimizing the need for frequent reinflation or mid-commute replacements.

Universal Schrader Valve Compatibility

Equipped with a standard automotive-style Schrader valve, this inner tube allows for effortless inflation. Because Schrader valves are the most common valve type globally, you can easily top off tire pressure using everyday floor pumps, portable hand pumps, or standard gas station air compressors without needing specialized adapters.

Improved Ride Comfort and Shock Absorption

A properly inflated high-pressure pneumatic tube acts as an essential suspension component. It effectively absorbs vibrations, small impacts, and threshold bumps, delivering a significantly smoother and more comfortable ride compared to solid urethane tires.

Broad Wheelchair Brand Compatibility

Available in common wheelchair wheel sizes, this versatile CST tube fits a wide array of manual rigid chairs, folding chairs, and sports wheelchairs from leading manufacturers like TiLite, Quickie, Ki Mobility, and Invacare. (Always verify your tire sidewall for exact sizing and pressure ratings before purchasing).
