Guide for Forklift Tire Size Chart

Choosing the correct tire size for your forklift is vital in enhancing its productivity as well as safety. This guide is comprehensive and provides all the necessary details with a chart that can be used to determine sizes depending on different needs or applications.

Understanding Forklift Tire Specifications

Not all tires are created equal, they have different measurements which make them fit and work properly. The main dimensions include tire diameter, width and rim size. It is important to know these figures so as to choose the right kind of tire.


The diameter refers to how tall or high a tire is from ground level up to its top part; this affects stability of trucks when loaded or unloaded from it.


This refers to how wide across the tread area of a given tyre is measured in inches. A wider one can provide more support thus offering better distribution of loads especially during heavy lifting operations done on rough surfaces such as construction sites.

Rim Size

It represents the diameter of wheel whereon an appropriate sized tyre will be mounted upon; ensuring that both match together tightly for safe operation.

Types Of Forklift Tires

There are various kinds available depending on what type truck you have and where it works mostly like indoor/outdoor use or terrain conditions. These include:

  1. Pneumatic Tires – These are air-filled just like those found in cars; best suited for rough pavements outside yards etc., as they give good traction plus smooth ride while minimizing shocks experienced by drivers at construction sites.
  2. Solid Tires – Also known as cushion tyres made out entirely from rubber without any space within them (solid); ideal choice would be warehouses having leveled floors where frequent punctures might occur due nails etcetera being left scattered around often.
  3. Polyurethane Tyres – These can be used indoors specifically designed for electric trucks; offer great load bearing capabilities with low rolling resistance which makes them perfect tools required during precision work carried out in factories or warehouses.

Factors To Consider When Choosing Forklift Tires

In addition to size, there are other factors that should not be overlooked when selecting these essential parts.\n

Load Capacity

Make sure you choose tires which can handle the weight being lifted by them. Overloading may lead to wearing off sooner than expected thereby posing a safety risk.\n

Operating Environment

Consider where yours operates mostly; whether indoors or outdoors on smooth or rough terrains respectively. For example, pneumatic types are ideal for construction sites while solid ones perform better at warehouses with flat floors.\n

Frequency Of Use

Think about how often the forklift will be used. Frequent usage in tough environments might necessitate more robust tires like solid or pneumatic tires with reinforced sidewalls.

Keeping up Forklift Tires

Proper maintenance extends your forklift tires life-span and guarantees safe operation. Regularly check the tires for any indication of wear, damage, or improper inflation. Rotate as necessary to promote even wear and change them when they are worn out.

Examination Tips

  • Check Tread Depth: Ensure that the tread depth is sufficient enough for safe use; otherwise, traction may decrease leading to accidents.
  • Look For Damage: Look out for cuts, punctures, or cracks that might affect the structural integrity of a tire.
  • Monitor Inflation: Regularly check air pressure levels on pneumatic tyres and keep them at recommended values always.

Indicators For Replacement

  • Bald Spots: When a tire becomes very smooth it shows signs of excessive wearing off which means less grips while driving.
  • Cracks And Splits: Any visible crack or split on a tire is an indication that it needs replacing soonest possible since this condition weakens its structure thereby making blowouts highly likely during operations.
  • Uneven Wear: If one notices uneven wearing then there could be alignment problems with his/her vehicle hence need correction before further damages occur due to poor contact between road surface and rubber compound.
