A crack in an alloy wheel is another problem which can occur from pothole collisions and hitting speed humps . Cracks will only get worse if they're not fixed and can cause your tyre to deflate slowly, which means topping up the air every couple of days. A cracked alloy wheel is also an MOT failure and dangerous.
