if you mean the wheels, take the lug wrench out of the trunk, pry off the hubcap if equipped, loosen the lug nuts of the wheel you want to remove 1 turn counterclockwise. raise and support the car with whichever wheel you want to remove off the ground, use the lug wrench to remove the nuts entirely, then slide the wheel off the studs. if you then want to remove the tire from the wheel, take it to a garage that changes tires...........you'll never get it off without a tire machine!
