The global air travel market is experiencing growth due to stringent safety regulations, increased demand for reliable and durable tires, and advancements in materials and designs. That's why the aircraft tire market is expected to expand from USD 2,030 million in 2025 to USD 3,705 million by 2035, according to Future Market Insights. The need for resilient tires to support heavy loads is also emphasized.

Costs for these tires range significantly due to differences in aircraft types and models, as well as the fact that main landing gear tires are often larger and more expensive than nose tires. The nose wheel always has a lower life expectancy than the rest of the wheels because of its steering capabilities and increased side loading pressure.

For example, a new Boeing 777 tire typically costs around $6000, whereas a B737 tire costs about $1500. Pricing might also vary depending on the manufacturer, as aircraft manufacturers rely on specialist contractors for their tires. The major players in aircraft tire manufacture are similar to those in automobiles, including Goodyear, Bridgestone, Michelin, Dunlop, and Wilson Oil Company.

Rolling through Airbus and Boeing

Preventive maintenance is crucial for cost efficiency, as early identification of potential issues can prevent significant damage and costly repairs. Aircraft tires, designed for extreme conditions during takeoff and landing, are specialized components, and prices vary based on aircraft model and tire specifications. Airlines often negotiate bulk orders, influencing final pricing.

The four major producers of aviation tires are Goodyear in the US, Michelin in France, Dunlop Aircraft Tyres in the United Kingdom, and Bridgestone in Japan. These companies dominate over 85% of the manufacturing business and account for the majority of retreads.

When landing in the world's hottest regions, these tires must withstand a wide range of temperatures, from minus 60 degrees Celsius at 10,000 meters to extremely high temperatures. They are tubeless, have a pressure of 12 to 18 bar, and are filled with nitrogen instead of air.

This difference ensures safety, as oxygen in ambient air could ignite when interacting with braking systems at high temperatures. Aircraft tires need to be changed every 120 to 400 landings, depending on the aircraft model, runway conditions, weather, and the pilot. Before each flight, the pilot or copilot must perform a preflight check, including a visual inspection of all tires to identify worn-out or objects stuck in the rubber.

Goodyear Flight Radial is a high-performance aviation product approved for use on leading aircraft such as the Boeing 777X, 737 MAX 8/9, 787-9/10, Airbus A320neo, Citation X+, Embraer Praetor 500/600, Gulfstream G500, G600, G650, Global 7500, and regional aircraft like the ATR 72, according to Goodyear.

Airbus tire price guide

Michelin supplies most of Airbus' civil aircraft, including the A350 XWB and A380 jetliners, which have the largest tires used in commercial planes, measuring 56 inches (142 cm) in diameter and 21 inches (53.34 cm) in width, with its Air X NZG (Near Zero Growth) radial tires, preparing for the next generation of long-haul jetliners.

NZG technology is designed to minimize tire growth. Aircraft tires have much higher inflation pressures (20 bar / 290 psi) than passenger car tires (2.5 bar / 36 psi) to support the aircraft's weight. At high speeds during takeoff and landing, centrifugal forces can cause the tire to "grow."

Airbus utilizes different providers for its tires, as Goodyear supplies its narrowbody jet A321XLR, offering advanced aviation features such as enhanced dimensional stability, longer lifespan, and cut resistance. Its radial construction allows for more landings and reduces weight through its optimized bead design. These tires feature featherweight Aluminum Core Bead™ Technology, achieving weight savings without compromising durability.

The A380 aircraft's landing gear consists of 22 wheels, each worth more than $5000 and weighing almost 120 kilograms. All wheels run at 135 knots (155.34 MPH, 250km/h) during landing, putting significant pressure on the tires. Nitrogen is used instead of air, as it can withstand extreme temperatures and prevent combustion during landing. Each tire is changed after 180–300 landings.

The price of Boeing's rubbers

The Michelin commercial radial aircraft tire (50 x 20.0R22 size) is designed for aircraft like the Boeing 747-400ER, 747-8, and 787-8; the average price for this tire is around $4,500 to $5,000 per tire. The B747 usually completes over 15,000 takeoffs and landings throughout its life. However, the B747 has a total of 18 tires (2 nose and 16 main), while the B787 utilizes 10 tires in total, with 2 on the nose landing gear and 8 on the main landing gear. The tire configuration number stands for:

1. 50: The tire's overall diameter in inches, measured from the ground up.
2. 20.0: The tire's width in inches, specifically the width of the tire's tread.
3. R: Radial tires are the most common type used in modern aircraft and vehicles, with layers of fabric arranged radially from the center of the tire.
4. 22: This is the diameter of the wheel the tire is designed to fit, measured in inches.

It has a speed rating of 235 mph and features 34 plies, which refers to the layers of reinforcing material in the tire. More plies are essential for handling heavy loads and high aircraft speeds. This tire is suitable for use on these aircraft models' noses and main landing gear for the 747-400ER and 747-8, according to Goodyear Aviation.

Meanwhile, the Boeing 777-200LR/300ER and 777F utilize 52x21.0R22 tires with a 36-ply rating for the main landing gear and 43x17.5R17 tires with a 32-ply rating for the nose landing gear, with different costs. The B787-9 Dreamliner employs 54x21.0R23 (38-ply) tires for the main landing gear and 40x16.0R16 (26-ply) tires for the nose, a specification it shares with the B787-10.

From a tire maintenance and safety perspective, some incidents highlight the importance of regular checks and upkeep of aircraft tires and landing gear components. From a cost-efficiency standpoint, preventive maintenance is key. Early identification of potential issues can avoid more significant damage and costly repairs while preventing potential flight delays.

The Tubeless vs. Tubed Debate

Tubeless tires do not have an inner tube inside them but a special sealant layer that prevents air from escaping through the tire's bead or the rim's valve. They are commonly used on aircraft and modern cars. Tubeless tires are designed to reduce weight, improve fuel efficiency, and prevent sudden deflation in the case of a puncture.

Tubeless tires are more expensive due to their advanced design and materials. They require precise engineering to create an airtight seal between the tire and rim, eliminating the need for an inner tube. Additionally, tubeless tires often include features like reinforced sidewalls, specialized rubber compounds, and built-in sealants.

One of the main advantages of tubeless tires is their lighter weight, which can save fuel and increase the aircraft's payload capacity. They also have lower rolling resistance, which requires less force to move and can improve acceleration and braking performance. They are also less prone to blowouts, as no inner tube can burst or leak. If a tubeless tire gets punctured, it will lose air gradually, allowing the pilot to land safely.

Tubeless tires are increasingly favored in aviation due to their enhanced durability, reduced maintenance, and improved safety, including Embraer and 👁 Image
ATR regional aircraft. They offer several advantages, such as weight reduction, reduced blowout risk, enhanced heat dissipation, lower maintenance costs, and improved sealing properties.

However, they are more expensive than tubed tires due to the need for special rims, valves, and sealants. They also have a shorter lifespan due to their susceptibility to wear and tear from heat, friction, and oxidation.

Unlike tube-type tires, tubeless designs eliminate the inner tube, reducing the risk of punctures and blowouts. This makes them particularly suitable for some aircraft that demand special performance. Tubed are also cheaper than tubeless tires, as they don't require special rims, valves, or sealants, reducing installation and servicing costs and offering a longer lifespan.

Tubed tires are less common in modern aviation but are still used in certain aircraft, particularly older models or those designed for specific purposes. For example, some general aviation aircraft, like older Cessna models, may use tubed tires.

Tubed tires are heavier than tubeless, increasing fuel consumption and reducing aircraft payload capacity. They also have higher rolling resistance, requiring more force to move and reducing acceleration and braking performance. Due to their inner tube burst or leak, tubed tires are more prone to blowouts or flats, which can cause rapid air loss, loss of control, or even a crash.
