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.  


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.

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.

Why do I have a temporary spare instead of a full-size one?

The use of donut spares is the result of limited space inside the vehicle in question or car makers seeking to reduce cost or weight. Typically the donut spare takes up much less space and is cheaper to manufacture than full size tires and wheels, which translates into more profit for the car makers. It also is significantly lighter than a full-size tire and wheel, which helps with fuel economy. Many cars eliminate spare tires of any sort altogether, and instead include a small tire inflator or can of tire goop, in the name of further weight savings and greater efficiency. Outfitting the car with run-flat tires is another frequent choice. These allow your to drive a comparable distance as the temporary spare would allow even with a full loss of air. The catch is they are much pricier to replace.

For the consumer, anything less than a full-size spare is quite a compromise in the event of a puncture.


Can I go 70mph on a donut? You can drive 70 mph, but this speed is not recommended. Exceeding the allowable travel speed is extremely dangerous because it can cause serious consequences such as tire explosion, loss of control from wheel wear. Although the speed figure depends on how the manufacturers manufacture, it ranges from 50-100 miles. However, you should limit the challenge and strictly follow the expert’s recommendations to be safe. Do donuts hurt your car? Some of the consequences of donuts cause to the car such as: – Car heating – Loss of power in the steering system – Hanging system – Burn the wall – Damage to the transmission of the steering unit. Can you drive faster than 50mph on a donut? You can do so, but we always advise against this. If you think that speeding does not affect you too much in a short time, this seems to be a completely wrong assumption. And no one can predict the future, so overusing tires can make you sick dangerously in traffic. Are donuts legal? The short answer is yes. It is widely available worldwide. And almost if anyone owns a car, there is a tire available. However, if you arbitrarily produce donut tires without the permission of the competent authority, you are violating the law on illegal activities.

How to Safely Use a Spare Tire?

Don’t use the spare tire if you experience a flat tire on one of the driving wheels. Instead, get the replacement from the non-driving wheel.

Replace the tire in the non-driving wheel with the full-size spare tire. As a result, you won’t feel a big difference in ride quality.

If you put a donut tire on a driving wheel, there is a huge shift in handling because it is undersized. It may throw you off the road when you turn or slide when you brake because there is much weight to carry.

If you don’t have a choice but to use the donut tire in front, drive a short distance. Don’t take other risks. Calling a towing service is a safer option if there’s a long way to go.
