They offer a long service life, low maintenance, and are puncture-proof. They provide excellent load-bearing capacity and stability.

2. Pneumatic Forklift Tires

Pneumatic forklift tires are similar in appearance to traditional vehicle tires, with an air-filled cavity. They are available in two subtypes: solid pneumatic (resilient) and air pneumatic (cushion).

Air-filled pneumatic tires offer a smoother ride, increased shock absorption, and better traction on outdoor surfaces. Solid pneumatic tires provide similar benefits but are puncture-resistant.

3. Cushion Forklift Tires

Cushion forklift tires are solid rubber tires without air-filled cavities. They are typically used in indoor applications on smooth, flat surfaces.

These tires offer stability, maneuverability, and a smaller turning radius. They are suitable for compact spaces and provide good traction on smooth floors.

4. Polyurethane Forklift Tires

Polyurethane forklift tires are made of a durable polyurethane compound. They are available in two forms: load wheels and drive wheels.

They provide excellent traction, long service life, and are non-marking. They are ideal for applications requiring minimal vibration and noise.

5. Non-Marking Forklift Tires

Non-marking forklift tires are designed to leave no scuff marks on floors. They are available in various types, including solid, pneumatic, and cushion.

These tires maintain floor aesthetics, making them suitable for clean and well-maintained facilities.

6. Ribbed Tires:

Ribbed forklift tires feature a ribbed tread pattern, offering improved traction and stability. They are available in both solid and pneumatic versions.

Ribbed tires provide enhanced grip on slippery surfaces and are suitable for applications where stability is essential.
