Planes are heavy. They just seem light when they fly in the sky.
The entire hull has to be extremely resistant to withstand different mechanical strains that arise when the airplane goes through different flight phases and performs sudden and sometimes completely unplanned maneuvers.
But the hull isn’t the only structural part that needs to deal with extreme forces. For example, how do plane tires survive not a single, but multiple landings? They are certainly kind of ‘delicate’ compared to metal, but nevertheless are able to support thousands of pounds of weight at high speeds without popping.
The following video gives the explanation what is the secret behind plane tires not exploding on landing:
