Understanding the Airbus A320 tire size is crucial for flight crews, engineers, and MRO teams. According to the Airbus A320 AFM (02-Apr-2025) and the A320 Basics Manual, the A320’s wheel and tire assemblies are designed for intensive short- and medium-haul operations, balancing weight, speed, and braking efficiency.
Main wheels and nose wheel configurations are specifically optimized for performance and safety, ensuring the aircraft operates effectively under various conditions. The A320 tire size plays a significant role in the overall performance of the aircraft, contributing to optimal brake unit functionality.
When considering the Airbus A320, it is essential to reference the component maintenance manual. These documents provide vital information about repair and overhaul procedures, ensuring compliance with OEM specifications set by manufacturers such as Goodrich, Safran, and UTC Aerospace.
For MRO teams, understanding the A320 tire size and specifications enables them to offer cost-effective solutions for lease and maintenance options. Rotable Repairs Ltd. can assist in exchange programs or loan arrangements for tires that meet operational requirements, ensuring that the aircraft remains airworthy within a suitable time frame.
Furthermore, Collins Aerospace and Messier support workshops that understand your requirements and will work with you to offer solutions that are suitable for your operation. By staying informed about the A320 tire size and associated specifications, MRO teams can maintain high standards of safety and efficiency in aircraft operations.
A320 Landing Gear Layout
The A320 uses a tricycle landing gear configuration with two main landing gear assemblies, each with two main wheels, and one nose landing gear assembly with two smaller wheels. This provides balanced weight distribution and excellent ground handling during taxi, takeoff, and landing.
A320 Tire Sizes and Pressure Ranges
| Landing Gear | Typical Tire Size | Pressure Range | OEM Manufacturer |
|---|---|---|---|
| Main Gear | 46×16.0R20 | 200–220 psi | Michelin / Goodrich / Dunlop |
| Nose Gear | 27×7.75R15 | 160–180 psi | Michelin / Goodyear |
Operational Speed and Tire Limits
- Maximum tire ground speed: 195 kt
- Maximum taxi speed: 20 kt (when > 76 000 kg)
- Landing gear extension (VLO): 250 kt (extension) / 220 kt (retraction)
- Gear extended (VLE): 280 kt / Mach 0.67
Approved Tire OEMs and Landing Gear Suppliers
The A320 landing gear is supplied by Safran Landing Systems. Approved tire OEMs include Michelin, Goodyear, Dunlop, and Collins Aerospace (Goodrich). All must meet Airbus Component Maintenance Manual (CMM) standards. For A320 tire replacement and maintenance, working with OEMs ensures compliance and reliability.
Weight, Brake Energy, and Tire Performance
Tire speed limits relate directly to Maximum Takeoff Weight (MTOW) and brake energy. For the A320-214 variant: MTOW 77,000 kg, MLW 66,000 kg, Max Brake Energy ≈ 37.5 MJ per brake, Max Brake Temp 300°C. These values affect turnaround planning, tire life, and aircraft ground handling systems.
Pilot and Maintenance Considerations
From the A320 FCTM and FCOM: Tire inflation must be verified during preflight walk-around. After a rejected takeoff, brake temps must cool before the next departure. Under-inflated tires may cause ECAM alerts or MEL restrictions. Proper landing gear maintenance is crucial for operational safety and efficiency.
Summary Table
| Parameter | Main Gear | Nose Gear |
|---|---|---|
| Tire Size | 46×16.0R20 | 27×7.75R15 |
| Pressure (psi) | 200–220 | 160–180 |
| Tire Speed Limit | 195 kt | 195 kt |
| VLO | 250 kt | 250 kt |
| VLE | 280 kt / M 0.67 | 280 kt / M 0.67 |
| Manufacturer | Safran / Goodrich | Safran / Michelin |
Closing Insight
The A320’s tire and gear system plays a crucial role in the overall performance and safety of the aircraft. With its carefully engineered tire size, the system achieves an optimal balance of load capacity, braking performance, and reliability, which are essential for the safe operation of flights.
Understanding these parameters not only aids in ensuring the aircraft operates efficiently and cost-effectively but also helps maintain compliance with the stringent requirements outlined in the component maintenance manual.
This knowledge is vital for aviation professionals to ensure that all operational aspects are adhered to, ultimately contributing to the safety and reliability of air travel.
