After only a short time, the tread starts to peel or separate from the steel core, so wheels must be replaced often at repeated cost. The problem lies in the quality of the tread and how it is bonded to the core.
The Real Causes
- Low-quality rubber: cheap rubber can't withstand friction heat and peels easily
- Poor bonding to the core: the tread is loosely fitted over the core rather than cast on as one piece
- Exposure to oil/chemicals: chemicals make the rubber degrade and delaminate
- Overloading + heat build-up: continuous heavy pushing heats the tread until it peels
The Hidden Costs
A peeling tread makes the cart jerk, risks goods falling, and means frequent stoppages to change wheels — in total you pay more than choosing durable wheels from the start.
How IRONMAX Solves This
- PU cast firmly onto the core: the PU tread is cast around the steel core as one piece and doesn't peel easily
- Resists friction heat: PU is tougher than ordinary rubber
- Oil/chemical resistant: doesn't degrade and delaminate like black rubber
Note: if you change wheels often because the tread peels, switching to cast-iron-core PU clearly reduces how often you need to replace them
