Are you aware that there are different kinds of spare tires? The type you have will vary depending on what kind of vehicle you drive. Here's a look from Nissan of Meridian at the two main types of spare tire.
A compact temporary spare, as its name suggests, is smaller and isn't meant to be driven very far. You should only keep it on your car for as long as it takes you to replace it with a new tire. You'll also want to be careful of your speed when using one. You may have heard these spares commonly referred to as donuts.
Unlike a donut, a full-size spare is larger and more solidly constructed. Big vehicles like full-size cars, trucks, and SUVs often come with this type of spare. You can drive at regular speeds and keep a full-size spare on your vehicle much longer than a donut.
