How to Measure and Read Forklift Tyre Sizes

The right forklift tyre is critical to safety, performance, and operational efficiency. Every forklift is engineered for specific tyre types and dimensions, carefully matched to its load capacity and intended use. Using an incorrect size can compromise handling and increase risks. That’s why tyre selection and fitting should always be managed by your material handling equipment (MHE) supplier or service partner. 

Why Is It Important to Know Your Forklift Tyre Size?

Understanding forklift sizes goes beyond convenience; it is a key factor in safety and performance.

• Safety and stability: Tyres that are too small or too large can affect the forklift’s centre of gravity, leading to instability and potential accidents
• Fuel and energy efficiency: Correct tyre size reduces rolling resistance, lowering fuel or battery consumption
• Handling and performance: The right tyres deliver smoother rides, better grip, and reliable braking

Using the wrong tyre size can cause uneven wear, damage to the forklift, and higher long-term costs. Always rely on your supplier to confirm and fit the correct tyres for your model.

What Do the Numbers on a Forklift Tyre Mean?

Every forklift tyre is marked with size codes that indicate its dimensions. Understanding these correctly helps you interpret what your supplier references during maintenance or replacement.

• Width: The measurement across the tyre’s tread, usually in millimetres or inches
• Rim diameter: The size of the wheel rim the tyre fits onto
• Overall diameter: The height of the tyre from the ground to the top of the tread

Example of tyre labels:

• 6.00–9 → 6.00 inches wide, designed for a 9-inch rim

• 200/50–10 → 200 mm wide, 50 mm aspect ratio, fits a 10-inch rim

How Forklift Tyres Are Measured 

Accurate measurement is an essential part of replacement and maintenance. During a tyre change or inspection, your MHE expert will:

1. Measure tyre width: Use a tape measure across the tread’s widest point
2. Measure tyre diameter: Measure from the ground to the highest point of the tyre
3. Check rim size: Measure the diameter of the rim where the tyre sits

These measurements ensure each replacement tyre matches the forklift’s original specifications, maintaining optimal safety and performance. If a different tyre size is fitted, the forklift must be re-rated to reflect changes in load capacity, stability and handling characteristics.

Should You Measure Pneumatic and Cushion Tyres Differently?

Yes. Different operating environments call for different tyre types, each measured and fitted differently.

• Pneumatic tyres, which are air-filled and often used outdoors, require measuring both width and overall diameter.
• Cushion tyres, which are solid and common in indoor environments, are measured mainly by width and rim diameter.

How Do Forklift Sizes Affect the Tyre You Need?

Different forklifts demand different tyres:

• Smaller forklifts (commonly used in warehouses) need compact tyres that enhance manoeuvrability and reduce wear on smooth surfaces
• Larger forklifts (for outdoor or heavy-duty work) require durable pneumatic tyres designed for stability on uneven ground

Always follow the manufacturer’s specifications and your supplier’s recommendations.

When Should Forklift Tyres Be Replaced?

Tyres should be inspected regularly to ensure safe operation. Look out for:

• Cracking or chunking in the rubber
• Flattening or “squaring off” of the tyre
• Reduced tread depth or smooth patches
• Uneven wear across the tyre surface

Worn-out tyres increase stopping distances, reduce grip, and can damage your forklift. Regular checks by trained technicians are part of effective fleet maintenance.
