Three questions before you choose
Look at the whole journey, including the least forgiving section.
What is under the wheel?
Describe the floor: smooth concrete, tiles, a coated surface or another finish. Note joints, thresholds, uneven patches and loose debris.
What matters most?
Is the priority quieter movement, protecting a finished floor, reducing effort or handling a particular loaded unit? Tell us what needs improving.
What does it carry?
Include the equipment’s own weight and its contents. Share how it is moved, how often it travels and whether conditions change along the route.
A starting point for your shortlist
Material families offer useful direction. The selected compound, wheel construction and operating conditions still need checking.
| Wheel tread | When to consider it | What to check |
|---|---|---|
| Rubber / elastic rubber | Where cushioning, quieter travel and floor preservation matter. | Compare the actual rubber compound and bearing. Confirm any non-marking requirement for your floor. |
| Polyurethane (PU) | Where you want to compare wear resistance, rolling behaviour and floor care together. | PU grades vary. Check the selected tread, wheel centre and application; one PU product does not represent every PU wheel. |
| Nylon | For smooth, firm, durable surfaces where easy rolling is a priority. | Its hard tread can be less forgiving of sensitive finishes and can transmit more noise across joints. Assess floor suitability. |
Read the tread and the wheel centre
The tread is the surface touching the floor. The rim or centre supports it. A black rubber wheel on a nylon rim still has a rubber tread; it is not the same choice as a solid nylon wheel. Read the full product description when comparing replacements.
Colour alone does not confirm a compound or its performance. Where marking, staining or a sensitive coating is a concern, ask about the exact product and trial it on a suitable sample area. Specialist temperature, chemical or electrical requirements need model-specific confirmation.
How it rolls depends on more than material
Wheel diameter, tread shape and hardness, bearings and the floor all affect starting and rolling resistance. Starting resistance is the effort to get moving; rolling resistance is the effort to keep moving. Compare the complete wheel specification when asking for easier handling.
Material is also separate from fitting and capacity. Check mounting dimensions, overall height, fixed/swivel/brake configuration and the selected castor’s listed load rating. Inyathi’s castor ratings are per castor; the complete equipment and operating conditions must be considered.
Help us match a practical replacement
For a hardware customer or your own operation, a clear description saves guesswork.
- A photo of the existing wheel, complete castor and equipment.
- The floor finish and any joints, thresholds, debris or other difficult sections.
- Loaded equipment weight, travel frequency and how it is moved.
- Your required quantities and delivery town.
- Any noise, marking, temperature, chemical or other specific requirements.
