Choosing the right rear wheel for a wheelchair is one of the most important decisions for performance, comfort, and durability. Whether you're a distributor sourcing replacement parts, a rehab supplier outfitting sport wheelchairs, or an OEM buyer specifying components for new builds, understanding rear wheel specifications is essential.
This guide breaks down every spec you need to know — and what to look for when sourcing from a manufacturer.
1. Wheelchair Rear Wheel Sizes
The most common rear wheel sizes for wheelchairs are measured by the overall wheel diameter (including tire):
| Size (Inch) | Size (mm) | Common Use |
|---|---|---|
| 22" | 559 mm | Youth, smaller users, indoor use |
| 24" | 540 mm | Standard adult wheelchairs |
| 25" | 559 mm | Sport wheelchairs, basketball |
| 26" | 590 mm | Tall users, racing, performance |
What to consider:
- Standard daily wheelchairs typically use 24" rear wheels
- Sport wheelchairs (basketball, tennis, rugby) often use 25" or 26" for better reach and speed
- Smaller wheels (22") reduce seat height and are better for shorter users or indoor maneuverability
Sourcing tip: Always confirm the rim size (ETRTO/ISO standard) in addition to the nominal inch size. A 24" wheel and a 25" wheel can share the same 559 mm rim — the difference is in tire thickness.
2. Wheel Materials: Aluminum vs Carbon Fiber vs Steel
The rim and spoke material directly affects weight, stiffness, and price.
| Material | Weight | Stiffness | Price | Best For |
|---|---|---|---|---|
| Steel | Heaviest | Moderate | Lowest | Budget, heavy-duty daily use |
| Aluminum | Light | High | Medium | Standard sport & daily use |
| Carbon Fiber | Lightest | Very High | Highest | Premium sport, racing, performance |
Aluminum Spoke Wheels
Aluminum is the most popular choice for wheelchair rear wheels. It offers an excellent balance of weight, durability, and cost. Most sport wheelchair rear wheels use aluminum rims with aluminum or steel spokes.
Carbon Fiber Wheels
Carbon fiber wheels are significantly lighter and stiffer than aluminum, making them ideal for competitive sports and premium builds. They reduce rotational weight, which means faster acceleration and less effort to push.

3. Spoke Types and Patterns
The spoke configuration affects wheel strength, weight, and aesthetics.
Common spoke types:
- Standard round spokes — most common, easy to replace, cost-effective
- Bladed/aero spokes — reduced air resistance, used in racing and high-performance sport chairs
- Mag wheels (no spokes) — solid spoke design, low maintenance, heavier, popular in basketball
Spoke count:
- 24 spokes — standard for daily use
- 28–32 spokes — heavy-duty, higher weight capacity
- 18–24 spokes — lightweight sport applications
4. Tire Types
The tire you choose depends on the surface and use case:
| Tire Type | Surface | Durability | Puncture Risk |
|---|---|---|---|
| Pneumatic (air-filled) | Outdoor, sport | Medium | Higher |
| Solid (airless) | Indoor, daily | High | None |
| Treaded | Outdoor, rough terrain | Medium-High | Medium |
| Slick | Indoor sport, court | Medium | Lower |
Key tire specs to specify when sourcing:
- Tire size (e.g., 25" x 1" / 559-25)
- Valve type — Schrader (car valve) or Presta (bike valve)
- Tire pressure (PSI) — typically 65–145 PSI for pneumatic
- Tread pattern — slick for courts, knobby for outdoor
5. Hub Specifications
The hub is the center of the wheel and connects to the axle. Key specs:
| Hub Spec | What It Means |
|---|---|
| Hub width | Must match the wheelchair frame's rear axle spacing (common: 125mm, 130mm) |
| Axle type | Quick-release (most sport chairs), bolt-on (standard chairs), or threaded |
| Bearing type | Ball bearings (standard), sealed bearings (low maintenance) |
| Bearing size | Common: 6000-2RS, 6200-2RS — must match hub and axle |
| Hub material | Aluminum (standard), carbon fiber (premium) |
Sourcing tip: Hub compatibility is the #1 cause of wheel returns. Always confirm axle diameter and hub width before ordering.
6. Key Specs Checklist for B2B Buyers
When sourcing wheelchair rear wheels from a manufacturer, use this checklist:
✅ Wheel Specifications

- Rim material (aluminum / carbon fiber / steel)
- Spoke type and count
- Tire type (pneumatic / solid) and size
- Tire tread pattern
- Valve type
✅ Hub Specifications
- Hub width
- Axle type (quick-release / bolt-on)
- Axle diameter
- Bearing type and size
- Hub material
✅ Commercial Terms
- MOQ (Minimum Order Quantity)
- Lead time
- Packaging (individual box / bulk carton)
- Available finishes (anodized colors, polish, matte)
- Custom branding / logo options
- Certifications (CE, ISO, FDA if required)
7. Common Wheelchair Rear Wheel Problems & Solutions
| Problem | Likely Cause | Solution |
|---|---|---|
| Wobbly wheel | Loose spokes or hub | True the wheel or tighten hub |
| Squeaking noise | Dry bearings | Replace or lubricate bearings |
| Frequent flats | Thin tire or wrong pressure | Switch to thicker tire or solid tire |
| Difficult to push | Worn tread or low pressure | Replace tire or inflate to spec |
| Wheel misalignment | Wrong hub width or axle | Check hub specs and axle compatibility |
