When one of your tires goes out, it is replaced with a donut tire (also called a spare tire, although a spare tire is typically the same size as a regular tire). The donut tire is intended to provide you with a means of transportation so you can get to the mechanic and have your tire changed as soon as possible. This tire is smaller, so it can be stored inside the vehicle and save space. Most owners’ manuals have a recommended mileage for the donut tire, with 50 to 70 miles being the average. If you are driving on a donut tire, it is best to get it replaced as soon as possible.

Here are a few things to note when driving with a donut tire:

  • Braking, handling, and cornering affected: Donut tires affect the braking, handling, and cornering characteristics of the vehicle. The donut tire is not as large as the traditional tire, which can decrease braking and handling. Furthermore, the vehicle dips where the donut tire is mounted, so the vehicle will tend to pull where the spare tire is located. Keep this in mind while driving so you can be better prepared for it.

  • Drive slower: Donut tires are not made to go as fast as conventional tires. This is because they are more compact, so the guideline is the spare tire should not be driven faster than 50 mph. While you can drive on highways with donut tires, it is safer to stay off of them as you will only be able to go about 50 mph or less.

  • Check your donut tire pressure: The safe air pressure recommended for the donut tire is 60 pounds per square inch (psi). Since the donut tire sits for a while without being inspected, it is a good idea to check the air once you put the tire on your car.

  • Safety systems disabled: Another thing to keep in mind when driving on a donut tire is that the electronic stability control and traction control systems will not work properly. Once a regular sized tire is placed back on the vehicle, both systems will work and you can drive like you did before. While they are off, keep in mind to take extra time and go a little slower to ensure your safety, and the safety of others.

Driving with a donut tire should only been done when absolutely necessary and for a short amount of time. Check the owner’s manual for the recommendation on how many miles you can drive on the donut tire. In addition, do not go over 50 mph while driving on a spare tire.

Hugh came to change out a flat tire for my spare today. I have to say that I feel sheepish for calling someone to come help because I know how to change a tire but I was at work and on shift until 2 am and he came to my place of work. Instead of just installing my spare, he took the time to evaluate the situation. I had a nail in my tire and he took the tire to get patched and my vehicle drove better on my way home than when I left this morning. It was snowing sideways when he showed up to help me. He was a bit of a godsend in the moment and I would recommend him to anyone. I was just distressed because I did not have enough tip to give this guy for overachieving when I needed it. Huge five star review. I only hope to pay his generosity forward. He was more than worth the cost and he did a phenomenal job.

How Long Can You Drive On a Spare Tire

Drive on a Spare Tire?

There are two things to consider when determining how long you can drive on a temporary spare tire. Those factors are distance and speed. You Should NOT drive on a donut for more than 50-70 miles. However, you can stretch this range to 90 miles or so if absolutely needed.

How To Put On a Spare Tire

Extra mileage is not a good idea, these tires are temporary for a reason. You should not attempt to drive long distances on these tires. Temporary spare tires come with such little tread to begin with.

You don’t patch a spare tire for the same reason you don’t patch a solo cup. It’s temporary cheap junk.

Tweet

Temporary spare tires are not designed to take on poor road conditions. They won’t be the same as a normal tire. So, any bump, projectile, or road hazard could cause your donut tire to blow out.

You can use a spare tire more than once. Just remember to check the tires wear conditions and PSI before using. If the tire does not pass the safety check, you should not use the spare tire. This means you need to buy a new tire.

Spare Tire and Jack

What PSI Should a Donut Be 

Understanding what PSI your tire should be at is critical to the safety of you, your car, and your passengers. A tire should be replaced, with a donut, when one of your tires blows out or goes flat.

A donut spare tire should have a pressure of 60 pounds per square inch (PSI). HOWEVER, you should always check your vehicle’s manual to find the correct pressure for your spare tire. Before you put your spare tire on your car or truck, there are a few things you need to check.

First and foremost, check your donuts air pressure. If your temporary spare tire is under inflated it is important to pump more air into it before driving off. It is important to keep a portable tire inflator in your vehicle’s trunk or car storage areas at all times in case of emergencies.

Another important safety factor that you need to take into consideration when replacing your tire with your temporary spare, is your other tires sizes. If your tires are not factory or stock, your donut tire may not allow your car to ride properly if installed with your new aftermarket wheels. It is always best practice to get a new spare tire if you upgrade your wheels.

How Fast Can You Drive on a Spare Tire

The second factor of safety to take into consideration when replacing a flat tire is the speed your spare tire can handle. How fast you drive on a temporary spare tire depends on your particular spare tire’s ratings. As a general rule of thumb you should never travel over 50 miles per hour (MPH) on your donut tire. It is best to avoid the freeway, to keep your speed down. Traveling at a speed greater than 50 MPH could cause further damage to your car or truck.

Life is fast. Are you living for what matters?

When regarding load capacity, speed capability, or all-weather traction, temporary tires are NOT designed the same as a normal tire. It is very important to check your vehicle’s owner’s manual and/or the temporary spare’s sidewall for instructions on proper use. This simple preventative measure could prevent a wreck, severe injury, or even death.

Your vehicles braking, handling, and cornering characteristics are going to decrease when driving on a donut tire. The donut tire will decrease your vehicle’s braking and handling due to that fact that it is smaller in size when compared to your other tires.

Additionally, your vehicle leans to or dips in the direction that the donut tire is. With this in mind, your vehicle will tend to pull where the spare tire is located. It is super important to understand what driving on a donut is going to feel/be like before taking off.

How Much is a Spare Tire

When looking to purchase a spare tire, it is important to know the difference between a spare tire and a donut tire/temporary spare tire.

A spare tire is a tire that is identical to the tires that are currently on your vehicle. This means that, that spare tire has the same load capacity, speed capability, or all-weather traction. These spare tires are typically on trucks, jeeps, or larger vehicles.

Unlike a spare tire, God is not a back up plan.

Tweet

A temporary spare tire, aka a donut tire, is a smaller tire. A temporary spare tire provides you with short or temporary means of transportation. These types of tires are usually on/in cars or smaller vehicles.

Now that you know the difference, it’s important to know where to buy the best and cheapest donut or spare tire(s). The answer is, some donut tires can be bought online for as low as $40. These tires are far more expensive at a tire retailer or mechanic shop. Where a spare tire can range dramatically is when it comes to the size and brand.

Can You Fix a Spare Tire?

A temporary spare tire can not be fixed or patched and is meant for limited use. The rubber simply isn’t thick enough to hold a plug reliably.

These tires have no belt and little to no tread. Most importantly, these tires are not reinforced. This means that these tires are already “fragile”. Drive on these tires with caution.

The temporary spare tire is simply made to get you to the repair facility you had your new tires shipped to. Find the right tires to ship to your local dealer! 

Symptoms of Spare Tires

There aren’t specifically symptoms of a spare tire, more so, there are signs that you need to put on your spare tire. Signs you need to put on your spare tire:

  • Flat tire
  • Leaking tire
  • Bouncing/rough ride
  • Loss of control
  • Sliding vehicle
