Every vehicle has a spare tire carrier. Do you know where yours is or how to get the tire off? If not, you may be stranded until someone comes along who can help you.
When one goes to buy a new or used vehicle they usually look at the options or gizmos on the auto. Few think to ask where the spare tire is carried, or how to get it undone so they can use the tire when they need it. This is one of the most important options as everyone will have at least one and usually more than 5 blowouts or flat tires during the time they own their car.
A great many cars have their spare tire carrier in the trunk of the auto. Most of the time it is under the rug in the trunk of the car. It can also be located along the edges of the trunk, with the side being the most common. Different auto makers have different choices for where they put these, so ask your dealer or the person you buy from where it is. If they have no clue, you need to shop somewhere else.
RV's usually have them mounted on the rear, in plain sight. They have a center mount bolt that you need to loosen to remove the tire which is usually covered with a vinyl covering. Trucks usually have easily spotted carriers under the rear end of the truck. These are a bit harder to get to as they require one to crawl or wiggle under the truck to get to them. Once you have gotten your spare from under the truck you need to replace it with the flat or you will have a dangling carrier that can make noise or hit other things under the truck. Worse case picture, that truck tire carrier can hang up on something and really damage your truck.
Spare carriers can go on bumpers or other parts of a vehicle that will support the weight of the mounting device and the tire. The look of a spare tire on the front end of any vehicle says. "I am ready for you, are you ready for me?" and gives you so much peace of mind, that you know that if anyone hits your front end, you are going to be ok. It also allows you very easy access to your spare tire. If you have to have someone help you change your tire, do you really want them to see what you have in your trunk? Also, you do not have to get out to let another person at your spare, you can sit safe in your car while the tire is fixed.
