How Long Can You Drive on a Spare Tire? (and How Fast Can You Go?)

‍How Far Fast Can You Drive on a Spare Tire?

The modern-day spare tire is a necessity in any car owner's arsenal of tools. A spare is typically used in the event of a flat tire, but someone who has one around can also use it to carry extra air for when they are on the road.

A spare tire is typically carried in the trunk of a car and is designed to be used quickly when needed by inflating with an air pump or deflating to fit in the trunk of an automobile.

A spare tire can be used in place of a standard one and can reach up to 50 MPH. But, depending on how it was driven on, the life span of the spare tire will vary.

Most spare tires have a driving distance of up to roughly 70 miles. This number can go a bit higher or lower depending on how it was used. After you hit the 70-mile mark, it is time to change your spare tire as soon as possible.

It is best to treat a spare tire as a temporary option and make the change right away back to a traditional tire. Spares cause your vehicle to drive unbalanced compared to a regular tire so longer-term usage can lead to vehicle issues.

How to drive safely on a spare tire

Regardless of whether your spare is a donut or a full-size spare, you’ll want to be careful while driving on it. To drive safely on your spare tire, follow these best practices:

  • Check your spare tire’s pressure regularly when it isn’t in use. Spare tires often have different inflation pressure needs than your regular tires, so it’s wise to check them for proper inflation. Plus, a spare tire isn’t much help if it has low pressure.
  • Give yourself extra space and time to brake. Using a spare tire can cause your vehicle’s anti-lock brake system (ABS) light to turn on, or for your ABS to not function properly. Additionally, a donut spare can lead to inaccuracies in some vehicles’ speedometers. Braking early and with extra space between you and other vehicles can ensure you’re not in for surprises.
  • Be extra careful when driving in inclement weather. Spare tires don’t have advanced treads, so they aren’t able to provide the traction your regular tires would. Spares are therefore more susceptible to slipping or hydroplaning (sliding across the surface of puddles). 
  • Replace your spare when necessary. Replacement will depend on the type of spare you have; check your vehicle’s owner manual, or inspect the spare for more information on how frequently you should replace it. Many spare tires have a lifetime of about eight years.

Run-Flat Tire (After a Puncture)

A Run-Flat is another of the spare tire types and

A Run-Flat is another of the spare tire types and is a good option for those that want to save weight in their vehicles, ditching the donut altogether along with the repair gear associated.

Contrary to popular belief, these tires can still be punctured and they should still be treated with care.

How Far Can You Drive?

You can drive about 50 miles on a punctured run-flat-tire. This is because the structure is built into the tire’s sidewalls, which allow your car to continue rolling down the road.

Obviously, if it is an extremely rough road, you might experience different results as you wear down the sidewall structure but I would keep it to 50 miles. You don’t want to end up stranded on the side of the road.

How Fast Can You Go?

Bridgestone (one of the four largest tire manufacturers) suggests one shouldn’t exceed 50 mph on a punctured run-flat-tire. If you exceed this speed, your vehicle’s handling, braking, and suspension dynamics could be compromised.

Can You Repair a Run-Flat Tire?

You can patch anything, but it is almost impossible to determine whether or not a run-flat tire has been damaged on the inside. This is why most tire manufacturers suggest you replace your run-flat tires as soon as possible after a puncture.

What Will Happen If You Drive Too Fast On A Donut Spare Tire?

Driving too fast with a donut spare tire is dangerous and increases the cost.

Dangerous situations will occur when you drive with the spare tire at a fast speed for a long time. The significant risk for the above problem is tire failure.

Traveling beyond 50 miles will not cause immediate consequences, but will certainly affect driving safety and many other dangers.

Unlike regular tires, a damaged donut can be worse than you think. With a limited design in many aspects, the risk of losing control of the vehicle’s power causes consequences for the rotating shafts and other parts of the car.

Although no country has yet issued an official regulation on spare tires, some traffic violations related to the donut also cost you a lot of money.

Keeping Cool When Things Heat Up

In the summertime, afternoon temperatures in Florida can easily get above 100 degrees. Johnnie, a tow provider with Meyers Towing, responded to a member whose car had stalled out on the side of the road.

What is the optimal speed for driving on a spare tire?

Although 50 mph is usually the limit, it really is not the speed you should be aiming for when driving on a spare tire.

As I mentioned above, the faster you drive on a spare tire, the more impact you will have on your car and the higher the risk of causing damage or have an accident.

As a result, it is a good idea to drive below 50 mph and proceed with caution when you do have a spare tire. Drive slowly, but make sure you do not create a hazardous situation by driving too slow for the road or conditions that may create unnecessary risks in people overtaking or having to slow down significantly.

If you have broken down on a high speed limit road, it is advisable to come off the road as soon as is practical and make your way to the nearest car repair or tire replacement center. On local roads, you can comfortably drive at 20 to 30 miles per hour which will not cause issues to other drivers and provide greater safety.
