A vehicle's spare tire is a critical piece of equipment, enabling drivers to replace a flat tire so they can safely get to a service station. But some drivers may be suprised to open their trunk and find a "donut spare", a compact, lightweight tire that is meant only for temporary use. Read on to learn what every driver should know about donut spares.

A Guide to Donut Spares

How do donut spares differ from regular tires?

Donut spares are much smaller and lighter than regular tires. This is to help reduce the overall weight of the vehicle and increase fuel efficiency. They also take up less space in the trunk. Rather than rubber, they are usually made of hard plastic and lightweight metal, which makes them easier to lift and move around when changing a flat tire on the side of the road. 

How far can you drive on a donut spare?

Donut spares are only a temporary fix to a flat tire. They are designed to help drivers get to a safe location where their regular tire can be repaired or replaced. As a rule of thumb, you should avoid driving more than 70 miles on a donut spare and at speeds no greater than 50 miles an hour.  

Does a vehicle handle differently on a donut spare?

Because of their small size, a car or truck will pull toward the side the donut spare is on. Their lack of tread can make driving in rain, snow, or ice more hazardous. They can also adversely affect how a vehicle corners and brakes. Driving slowly and keeping your hands firmly on the wheel can help avoid accidents while using a donut spare. 

How does a donut spare affect the vehicle?

On most vehicles, the differential only activates when turning a corner or driving on a curve, enabling the left and right tires to spin at different speeds. But when using a donut spare, because of its smaller size, the differential will run continuously, increasing the wear and tear on the system and raising the risk of serious damage. Having a flat tire repaired or replaced as soon as possible and limiting how far you drive on a donut spare will help avoid costly mechanical issues. 

What maintenance does a donut spare need?

Regularly checking your donut spare's air pressure will help ensure it is ready when you need it. Most donut tires should be inflated to about 60 pounds per square inch (PSI). Like regular tires, a donut can break down over time. Have a mechanic inspect it for any damage when you have your regular tires rotated every 3,000 miles.
