What material are airplane tires made of??

¿Sabes de qué material isán made the tires or pneumaticátics of the planes? In this installment I tell you about its particular character.ícharacteristics that make them so resistant.

exposed to large speeds, impacts and extreme operating conditionsón, Aircraft tires are key parts in the security toérea and in a capíLet's Talk about Aviation titleóThey asked me this question.

Before a clarificationón, comúThe tread rubber is simply called a tire. (change país in país), but really that part is the tireático, but it is an expressionón less used. The rim is the metal part that the tireático protects, but for reasons of practicality we will say rim as it is the expressionón howún máfrom usada.

visually, very similar to the one you use día a díand here by carówill, but with a big difference, they are much más resistant for everything they must resist día a día.

Image onlyínate how resistant they are to support hundreds of tons of weight at más de 250 kilómeters per hour at the moment of hitting the runway (wasígrandfather'són in avión) and rarely presenting failures, all this thanks to the engineeríwith those that have been designedñadas and its materials.

¿From whaté Eastán airplane tires made?

just like cars, its main material is rubber, but this is driver. Conductive rubber is a materialáthat's what it isá diseñado specíphysically to conduct electricity that is generated by frictionón during the different stages of the flight.

The portal aviationpros.com goes más allá and offers us informationóDetailed description of each of the tire layers:

• tread: The tread isá made of rubber mixed with other additives to obtain the desired level of  durability and wear resistance.
• side wall: the sidewall is a protective layer of rubber that covers the outer shell layer. It extends from the edge of the tread to the áarea of ​​suchón.
• tread reinforcement layer: one or más layers of fabric that strengthen and stabilize the átread area for one operationón at high speed. Spaghettién serves as a reference for the polishing process when retreading tiresáticos.
• Takeín Buff Line: The fuckín Buff Line está made of a rubber compound to improve adhesion between the tread reinforcement layer and the breakers or carcass layers.
• breakers: Breakers are reinforcing layers of rubber-coated fabric placed under the cushion.ín of the lípolishing line to protect the shell layers and strengthen and stabilize the átread area.
• carcass layers: alternating layers of rubberized fabric (that extend into áopposite angles to each otherí) provide tire resistanceático.
• wire beads: High tensile steel wire hoopsón that anchor the carcass plies and provide a firm mounting surface on the wheel.
• Apex Strip: one withñrubber affixed to the top.
• fins: Layers of rubber fabric help anchor the talon wiresón to the casing and improve the durability of the rim.
• folds: The lining folds are anchored wrappedéwrapping them around the wire strands.
• Chafer: A protective layer of rubber and/or fabric located between the carcass and wheel plies.
• Coating: in the tiresáticos without cámara, The liner is a low permeability rubber layer that actsúas a built-in tube and prevents gas from moving to other layers.

¿Con qué they inflate?

One of the best questions and the main difference from ordinary tires. On airplanes their tires are inflated with nitrógeno

¿To whaté presióthey do not inflate?

Varying from the avi modelón, are normally inflated to an average of 200 psi (Pound per square inch) which is equivalent to about six times what is used to inflate car tires.

¿From whaté tamañor is it the tires?

It depends a lot on each avión, but as a reference a Boeing 737 It has tires of 68 centímeters of theámeter and 19 centímeters wide on a rim 15.

¿Becauseé smoke comes out of the tires on landing?

The moment of «impact» of the tire against the asphalt of the track, is están skating, not turning. At that moment the avión práIt practically drags the tires along the track until they equal their rotational speed.ón with the speed of the aircraft, That is why the smoke that we like to see so much on landings is generated..
