Jacks and lug wrenches for emergency replacement of a flat tire with a spare are included with a new car. Not included, but available separately, are hand or foot pumps (like a bicycle pump) for filling a tire with air by the vehicle owner. Cans of pressurized air can sometimes be bought separately for convenient emergency refill of a tire.
New cars usually come with jacks and lug wrenches to change a flat tire using a spare. However, owners must buy hand or foot pumps separately if they want to inflate their tires manually. Some people also buy cans of pressurized air for quick re-inflation of their tires in case of an emergency.
