Types of Forklift Tires and 5 Key Indicators for When to Replace Them

            Like regular vehicle tires, forklift tires—particularly solid tires—also have a limited service life and must be replaced when worn. Generally, there are two main types of forklift tires: solid tires and pneumatic tires. Each type has distinct characteristics and is suited to specific applications. This article will explain the differences between these two tire types and present five important signs that indicate when it’s time to replace your forklift tires—guidelines that apply to both types.

Types of Forklift Tires

           Forklift tires fall into two primary categories: solid tires and pneumatic tires, each designed for different operational needs. Below is a breakdown of their characteristics, advantages, disadvantages, and recommended usage.

Solid Tires (Cushion or Press-On Tires)

           Solid tires with tread are the most commonly used due to their exceptional durability and minimal maintenance requirements. These tires offer a longer lifespan compared to pneumatic tires and are resistant to punctures and tears, making them ideal for both indoor and outdoor use—even on uneven surfaces or areas with sharp objects. Since they cannot go flat, they also reduce the risk of accidents due to blowouts, enhancing safety.

Solid tires come in several subtypes:

• Black Solid Tires: Standard solid tires for general use, typically outdoors.
• White Non-Marking Tires: Designed for indoor environments and industries requiring high levels of cleanliness.
• Anti-Static Tires: Ideal for electronics or flammable material industries where static electricity can pose safety risks or damage sensitive components.

At Jenbunjerd, we offer solid tires from leading manufacturers such as Dunlop, Greckster, Pio-Tyres, and Tokai.

           In addition to treaded solid tires, smooth tread (cushion) solid tires are also available. These tires have a tighter turning radius and are ideal for operating in narrow aisles or compact indoor spaces. However, they are not suitable for rough surfaces such as gravel, as their lack of tread can reduce traction and cause damage to certain floor types. For this reason, smooth solid tires are not commonly used in Thailand.

Pneumatic Tires

           Pneumatic tires are similar to those found on passenger vehicles. They are air-filled, with deeper tread patterns that provide a smoother ride—especially on rough or uneven terrain with potholes. These tires are suitable for both indoor and outdoor use, but not recommended in areas with sharp debris such as nails or metal shards, as they are susceptible to punctures and air leaks.

Pneumatic tires require regular maintenance, including air pressure checks, to prevent underinflation, excessive wear, or blowouts, all of which can compromise safety. Due to these vulnerabilities, pneumatic tires generally have a shorter lifespan than solid tires.

Choosing the right tire type for your forklift is critical to ensuring optimal performance, prolonging tire life, and reducing the frequency—and cost—of replacements.

Now let’s explore the 5 key signs that it's time to replace your forklift tires.

5 Signs It's Time to Replace Forklift Tires

1. Wear Reaches the Safety Marker

            This is the most common method for checking tire wear. Most forklift tires include a safety line or marker that indicates the wear limit. If the tire tread has worn down to this level, it’s time to replace the tire immediately to ensure safe operation.

2. The “2-Inch Rule”

            For cushion (solid) tires, apply the "2-inch rule." If the height of the tire has worn down by two inches from its original height, it’s time for a replacement.

3. Decreased Traction and Tire Separation

            If you notice the rubber separating from the inner steel rim, your tire's traction and integrity have deteriorated. A simple test: insert a flathead screwdriver or knife into the gap—if it fits, it's a clear indication that the tire should be replaced.

4. Visible Damage or Tread Wear

            If the tire shows cracks, punctures, or visible damage, even if it’s just one tire, for safety and stability it is recommended to replace all four tires simultaneously. Additionally, if the tread becomes smooth or slippery to the touch, it indicates excessive wear—prompt replacement is advised.

5. Expired Shelf Life

            Even if a tire has not been used, it still has a limited shelf life. Check the manufacturing or expiry date on the tire sidewall—usually marked with a year—to determine whether the tire has passed its usable lifespan.
