How Long Can I Drive on a Spare Tire? 

We’ve all been there—driving along when suddenly you hear that dreaded flapping sound of a flat tire. Whether you're a pro at changing tires or not, having a spare tire is always a lifesaver on those not-so-great days. Once the spare is on, you’re back on the road, but it’s important to remember that spare tires are not permanent solutions. 

So, how long can you actually drive on a spare tire? Let’s break it down, because it depends on the type of spare tire you have. 

A Space-Saver Spare Tire (or Donut) 

If you’ve noticed that your spare tire is smaller than your regular tires, you likely have a space-saver spare, often called a "donut." These smaller spares are designed to save space in your car, which allows manufacturers to build more compact vehicles. 

While space-saver tires are great for emergencies, they are not designed for long-term use. They typically have almost no tread, making them hazardous for extended driving. Here’s a general rule of thumb: 

• Don't drive more than 70 miles on a space-saver tire. 
• Don’t exceed 50 mph while driving with it. 
• Always check your owner’s manual after installing a space-saver spare for exact details. 

In most cases, it’s best to avoid highways and interstates when driving on a space-saver tire, as higher speeds and long distances increase the risk of failure. 

While they’re convenient in a pinch, it’s crucial to get a full-size tire installed as soon as possible. 

A Full-Size Spare Tire 

Unlike space-saver tires, a full-size spare tire is the same size as your regular tires, offering more durability and the ability to drive longer distances. These are not common in compact cars due to the extra space they take up, but they provide much more peace of mind if you get a flat. 

You can typically drive on a full-size spare just as you would with your normal tires, but keep in mind it’s probably not from the same manufacturer as your other tires. This could mean the tire handles slightly differently. While a full-size spare can buy you more time, we still recommend replacing it with a matching tire as soon as possible to ensure optimal handling and safety.
