Is There a Difference Between a Spare Tire and a Donut?


Depending on the make, model, and type of vehicle you drive, you could either have a spare tire or a donut. There is a difference between these two “back-up” tires you can use when you get a flat tire.

New Car Tires

Spare tires are full-size tires that are the same size as your existing tires. They allow you to drive normally without any noticeable changes in handling or performance. If you have a full-size spare tire, it is highly recommended you include this tire in your regular tire rotations to make sure they are properly filled with air and wear evenly along with the other tires on your vehicle.

On the other hand, donuts are a temporary spare tire . They are much smaller than your regular tires and are only meant for short distances until you can get a new full-sized tire. You should not drive at high speeds on the donut or drive on it for an extended period of time. In addition, the performance and handling of the vehicle will be noticeably different.

Donuts should be inspected anytime you get your other tires rotated to verify it has the correct amount of air. They also need to be replaced periodically, as the rubber will harden over time and could easily blow out if the tire is too old.
