You mean pop vehicle tyre?

That's what I've made so far, but I don't have time to finish it, because College and work are calling me. You can edit it, if you want. For now that function checks both front & rear wheels positions, but it's not possible to shoot them, because your position must be EXACTLY the same as wheels position. Just make a range of shooted position, and check is it around wheels.
