In a recent project for a client in Australia, H40 aircraft tyres required four 100 mm holes to be drilled according to an approved tire-chain net drawing.
While the modification itself was relatively straightforward, it highlights an important aspect of pneumatic fender manufacturing: aircraft tyres are rarely used exactly as supplied.
Although aircraft tyres are widely used in pneumatic fender tire-chain net systems because of their durability and wear resistance, most projects require them to be adapted to match specific assembly requirements. Hole quantity, hole diameter, and hole position often need to be customized to suit the final tire-chain net configuration.
The Role of Aircraft Tyres in Pneumatic Fender Systems
In a typical pneumatic fender installation, the outer tire-chain net protects the fender body from abrasion, impact, and mechanical damage during operation.
Aircraft tyres are commonly selected for this purpose because they offer:
- High durability
- Excellent wear resistance
- Long service life
- Reliable performance in demanding marine environments
As part of a complete Marine Fender System, the tire-chain net helps extend the service life of Pneumatic Rubber Fenders operating in ports, terminals, shipyards, and offshore facilities.
However, the tyre itself is only one component of a much larger assembly that includes chains, shackles, rings, and other Marine Hardware.
Why Hole Position and Hole Size Matter
Aircraft tyres used in tire-chain net systems frequently require drilling before assembly.
The location, diameter, and quantity of holes directly influence how the tyre connects with:
- Chains
- Shackles
- Connecting hardware
- Net support structures
Even relatively small deviations can create installation challenges.
Incorrect drilling may prevent chains and hardware from aligning properly, resulting in assembly delays, additional modification work, or unnecessary installation difficulties on site.
For this reason, drilling specifications are normally determined according to project drawings rather than relying on standard tyre configurations.
The objective is simple: ensure that every component fits together correctly once the tire-chain net is assembled around the pneumatic fender.
Why Drawing Approval Matters Before Production
For customized components, drawing approval is often one of the most important stages of the manufacturing process.
Before production begins, details such as:
- Hole diameter
- Hole location
- Hole quantity
- Tyre specifications
should be reviewed and confirmed by both the supplier and the customer.
This process helps ensure that the final product matches the intended assembly design and reduces the likelihood of problems being discovered after shipment.
In many cases, a brief drawing review can prevent costly delays during installation.
A Project Example from Australia
The Australian project involved H40 aircraft tyres intended for use in a pneumatic fender tire-chain net system.
According to the approved drawing, each tyre required four drilled holes with a diameter of 100 mm. The drilling requirements were reviewed and confirmed before production to ensure compatibility with the client’s tire-chain net configuration.
By verifying these details in advance, manufacturing proceeded efficiently and the risk of installation issues during final assembly was significantly reduced.

Conclusion
Aircraft tyres are an important component of many Marine Dock & Mooring Fender Systems, but they are rarely used exactly as supplied.
Project requirements often dictate modifications such as custom drilling to ensure compatibility with chains, shackles, and other assembly components. Paying attention to details such as hole diameter, hole position, and drawing approval can help improve installation efficiency while reducing the risk of costly adjustments later.
For many marine projects, successful installation depends not only on selecting the right components, but also on ensuring that every part of the system is manufactured to match the intended application. A well-coordinated assembly process helps improve reliability, simplify installation, and support the long-term performance of the entire marine fender system.
