Projectiles are objects that are thrown or shot through the air. They are typically small and have a pointed shape. Some common examples of projectiles include bullets, arrows, rocks, and javelins.
Tires, on the other hand, are large, round, and made of rubber. They are not typically used as projectiles because they are not aerodynamic and would not travel very far. Additionally, tires are too heavy to be easily thrown or shot.
Therefore, a tire is not a common projectile.
