A car engine basically has thousands of mini explosions happening inside of it, is has parts moving very fast and generating tons of heat, and experiences extreme temperature fluctuations on a daily basis. Yet it is the part that usually dies last in a car.
How do they make them last so long and why are we unable to make other parts of the car as long lasting, such as tires and brakes?

All the parts of an engine are designed to reduce friction as much possible. Everything is oiled, everything is machined to very specific tolerances to be smooth and uniform and not stick.
Tires and Brakes are designed to increase friction as much as possible. They are designed to be sticky, for tires to stick to the road to direct the car, for breaks to be able to dissipate the momentum of the car as heat.
Because they are sticky little bits wear away as they are used. So eventually they have to be replaced. The really astonishing thing is how long they actually last.
