Aleader solid rubber wheels

Aleader solid rubber wheels are built with polyurethane foam and need no inflation. Each wheel comes with a tyre and wheel rim as one complete assembly.

The tyre outer layer is wear‑resistant rubber, and the inner core is high‑density polyurethane foam. This design gets rid of conventional inflatable structures, delivering both elasticity and solid support.

Thanks to the foam's cushioning effect, these wheels soak up road shocks. They weigh less than full‑rubber solid wheels and stand far better against punctures than air‑filled tyres, so blowouts are no longer a concern.

Versatile for multiple types of equipment, the wheels support custom sizes, load capacities and tread patterns. They fit wheelchairs, hand carts, small machinery and other applications.

The one‑piece construction keeps maintenance work and costs low, performing well in outdoor and industrial settings. They bring together long‑lasting durability and smooth ride comfort, serving as a practical replacement for both pneumatic tyres and all‑solid rubber wheels.

Unique Material & Structural Merits

Different from thin-walled small-size PU wheels, this 12.5-inch model adopts gradient density foam internal framework. The outer contact layer uses high wear-resistant formula to slow tread loss on rough roads, while the inner elastic foam core absorbs road bumps efficiently. The integrated seamless forming removes hidden gaps inside the tyre, so the wheel won't sink or deform under long-term continuous load. All raw materials contain no toxic volatile substances, passing international eco-test standards and meeting safety rules for medical and daily transport products.
