It's construction is very similar to a car tire. Actually exagerated. Construction is quite dissimilar to a car tire: 1) there is only a very small proportion of radials, eventhough the advantage over crossed plies is considerable and all recently qualified major planes are radialized; 2) for radials, there are no crossed plies in the belt, in part to make sure the tire has no cornering stiffness, so that when the plane lands in a cross-wind the tires do not produce cross (Y) forces despite rolling at a large slip (cornering) angle. And for mass reduction and strength, steel is restricted to the beads; crown/belt is almost always nylon. Ergos.
