How far can you go with a flat tire


How Far Can You Drive on a Spare Tire?

If you have a flat tire, you know how frustrating a process it is to get your car back to its normal operation. Not only does it disrupt your travel, it also takes time and money to replace a flat. After you change the flat tire and install your spare, you might be wondering: how long can you drive on it?

In this article, we’ll tell you just how far you can drive on a spare tire, what the key differences in types of spare tires are, and best practices for driving on a spare tire.

Let’s jump right in by answering your main question: 

You should drive no more than 50 miles on a temporary or donut spare tire if possible. If you absolutely must go longer than 50 miles, avoid driving on it longer than 70 miles. A spare tire isn’t meant to completely replace a tire, rather, its purpose is to tide you over until you can properly replace it.

Additionally, you shouldn’t drive faster than 50 mph on a temporary or donut spare tire, as they have far less traction and durability than a standard tire. You probably wouldn’t want to drive longer or faster on a spare anyway, as the typical spare can make your vehicle feel more like an airplane ambling down a runway than a car driving down a highway.

Once you are driving your spare, you should replace it with a proper full-size tire as quickly as possible to stay safe on the roads.

Types of Spare Tires:

There are several kinds of spare tires, but which one you will use mostly depends on the type of vehicle you’re driving.

  • Compact and Midsize Cars: Small to midsize cars often use compact temporary spares, often referred to as ‘donut’ tires. These are small tires that usually fit inside your vehicle, beneath the floor of the trunk. These tires not only differ from regular tires in their shape and size, but also in their required tire pressure. While most tires for smaller vehicles require a tire pressure around 35 PSI or so, these spare tires often require around 60 PSI.
  • SUVS, Crossovers, and Trucks: Larger vehicles will often come equipped with a full-size spare tire. These vehicles are significantly heavier than most sedans and mid-sized cars, so the spare tires are usually larger to support the vehicle’s full load, and possibly additional cargo or items being towed.

Full-size spares are typically much better quality than a donut spare; however, they still should be replaced as soon as possible. These spares often aren’t as durable, may have narrower wheels than the standard tires, and may not be produced by the same manufacturer as your other tires.

Full-size spare tires should be regularly inspected too, especially if they are secured to the bottom of the vehicle and therefore may be exposed to harsher elements.

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.

How Far Can We Drive on a Flat Tire?

If you must drive with a popped tire then make sure that where you’re going is relatively near.

The limit is 50 miles just right after the tire got punctured. However, you must prepare for any potential damage to your car.

However, flat tires shouldn’t be driven long distances. You’ll risk damaging your vehicle more, notably the wheels, brakes, and other parts such as your suspension and steering system.

Damage to these vehicle systems can drastically reduce handling, not to mention repair costs.

Why Experts Don’t Recommend Driving On A Flat Tire?

It’s tempting to drive a short distance on a flat tire. However, it’s better to drive on a spare tire instead, provided you have one ready.

If you don’t have considerable damage to it, the puncture could potentially be plugged and save you the hassle and money of getting a new one.

Suppose you need to drive a short distance on a flat tire. Just make sure that you’re going slowly.

  • It’s best to stay less than 50mph since, at this speed, you’ll have better control of the vehicle and move without damaging the rim.
  • However, if you completely lose pressure in your tires, I’m afraid you only have a 5-mile window.

If you’re asking, “can I drive a flat tire 2 miles?” .5 more than the recommended distance. Technically you can, but you’ll have to be ready for additional vehicle damage.

Furthermore, the most significant scare would be traffic accidents. As your car mishandles, the chances of getting traffic accidents rise exponentially.

One unintentional turn or stoppage when you ride on a flat tire is a one-way ticket to disaster.

How Long Can I Drive on a Spare Tire?

Spare tires are essential when you’re driving. Having one can save you the hassle of driving slowly yet dangerously as you go on a flat tire, not to mention that a spare tire is a requirement in most state traffic laws.

  • When driving with a spare tire or a donut spare, 50 miles is the safest distance.
  • If you must push it, your vehicle can potentially achieve a 70-mile stretch.

Luckily, this is a lot better than driving on a flat tire. The time and hassle of changing a flat tire are worth it.

Spare tires are, as the name suggests, a spare. When driving with one, ensure you find the right kind of wheels for your car as soon as possible. Not only would this dramatically improve your handling, but you’ll mitigate the risk of popping another tire, this time without a spare.

How to Replace a Flat Tire?

When replacing a flat tire with a spare, you must follow several steps to ensure safer and more efficient work. These steps apply to your front or rear tire.

Step 1: Make sure you pull over safely

If you decide to change your tires instead of driving on, pull over on the safe side of the road.

Also, place a warning device to let oncoming traffic know you’re in a dire situation.

Step 2: Make sure you have tools and a spare tire

You’ll need at least three tools when changing a tire on your vehicle.

  • Jack
  • Tire iron
  • Spare tire

Additional tools can be:

  • Fresh flashlight
  • A pair of working gloves
  • Mat
  • Tire pressure gauge
  • Vehicle’s manual

Step 3: Loosen the lug nuts

Using a tire iron, loosen each lug nut on your wheels until you can easily turn them manually with your hands.

Step 4: Lift the vehicle

Raise your car by placing the jack underneath the metal part of your vehicle. Avoid placing it under the plastic frame.

To best do this step, consider referring to your owner’s manual for additional assistance.

Step 5: Remove the tire

Carefully remove your tire by removing the lug nuts. Ensure that the lug nuts are in a safe box. Then, pull the tire towards you to take it out.

Step 6: Place the spare tire

Carefully place your spare tire, and using your hands, place the lug nuts, but don’t secure them just yet.

Step 7: Slowly lower your vehicle

Lower your car and tighten the lug nuts while the tire slowly touches the ground.

Step 8: Ultimately, lower your vehicle

Lower your car and secure the lug nuts as tight as possible. You’re now ready to drive your vehicle.

I quickly looked through Reddit for some pro tips, and I saw that u/Grosse Fahrt advised that a donut spare can potentially damage the drivetrain if you place it on your drive axle. So a spare full-sized identical wheel is better to keep around.

How Can I Prevent a Flat Tire?

There are many ways to prevent a flat tire, as prevention is better than cure. However, you must also be ready as even the most vigilant drivers can still have one, mainly due to wear and tear.

  • Regularly check tire pressure – Routinely check your tire pressure since a decrease in tire pressure could significantly raise your chances of puncturing your tire.
  • Stay aware of how much weight your vehicle can handle – Each car has a maximum weight capacity. Ensure your tires are safe by not exceeding the recommended capacity.
  • Rotate your tires if needed – Rotate them every 6,000 to 8,000 miles to maintain their durability. It’s also a great way to inspect your tires’ overall condition.
  • Make sure that your brakes are in good condition – Your brakes are directly linked to your wheels, and a poorly adjusted brake system can eventually wear your tires down. A mechanic is more than capable of doing this for you.
  • Be careful when driving – Hazardous road conditions or artifacts can damage your tires, so always be on the lookout. Another case is driving off-road with wheels that aren’t suited for the rougher road can also potentially damage your tires.

Conclusion

Most of us have driven on a flat tire at some point. Whether for a short period or longer, driving on a flat tire is never something you want to do.

Certain factors might cause you to drive with a flat tire, such as lack of spare tire, limited ability to change the tire along the way, etc.

Knowing “how far can you drive on a flat tire” will help you get out of the situation without damaging your vehicle or, most importantly, yourself if you are ever in this position.

2 sets of wheels or overboarding - which is more profitable?

Situation 1. There is a pump in the trunk (but there is no spare)

Inflate the tire to three atmospheres and move off. After 3-5 minutes of travel, stop and check how much the pressure has dropped. At about one, grab the pump again. And so on until you reach the right place.

Situation 2. There is nothing to pump up

At a speed of 40 km/h on smooth asphalt with a flat tire, you can safely drive about 2 km. Moreover, most likely, after such a feat, the tire will be able to be pumped up and operated further.

Situation 3. The tire "expired" in motion

An extra ten meters will not make the weather. After all, it is not clear how much you have already traveled on an "empty" wheel. So don't stop in the middle of the road. It is better to smoothly turn to the side of the road, and if there is a side platform within sight, slowly reach it.

Situation 4. A flat tire suddenly

For example, a sidewall puncture has occurred. There is nothing to lose - it will not be possible to reanimate the tire for further operation. But you can stretch 40 km / h from a dozen kilometers to a tire fitting. Be careful: closer to 15 km, the tire will start to smoke, crunch and fall apart. "Debris" can damage the apron, locker or bumper plastic. It's better not to bring it up.

Life hacks for every situation:

  • With an increase in speed (or on a gravel road), the amount of "empty" run will be reduced significantly.
  • No sudden movements! Do not brake hard or steer. First, you can lose control of the car. Secondly, these actions will provoke the rotation of the rubber on the rim, which will accelerate its destruction.

Is it harder in the cold? Vice versa!

The colder it is outside, the longer it will take for the tire to reach critical temperature and the further you will drive. But in the heat, the tire warms up faster, which means that the range will be reduced.

What determines the durability of a wheel?

First of all - from the strength of the sidewalls and carcass of the tire. A thick sidewall will help you get to the tire shop, a thin sidewall will “die” much faster. Therefore, on a crossover (SUV tires have reinforced sidewalls) you will drive further under the same conditions than on a passenger car.

    Articles about technical information and tire characteristics

    On the road, various troubles can happen to a car and a rubber puncture on a car is a common case.

    The absence of a spare wheel or a standard "roll-in" seriously complicates the situation. If the driver has the skills, you can put a temporary patch on the puncture, otherwise you will have to order a tow truck.

    We recommend that you carry a spare wheel, a repair kit for various occasions, and the necessary tools, then you can get out of any traffic situation with dignity. If all this is not there, then you can drive on punched rubber a short distance to a service station or tire fitting. We are not talking about hundreds of kilometers of travel, we are talking about a short distance.

    Causes of loss of pressure

    Leakage of air from a car tire can occur in different situations. At the same time, punching is not necessary, there are other unforeseen and unpleasant situations. Most common:

    • A puncture is the most common accident on the road. In this case, the situation may worsen if the puncture is slow, that is, a sharp object is stuck in the tire and the air comes out very slowly, the driver will find out about this later, when it is completely lowered. In this situation, if a puncture is detected, you can slowly drive to the tire fitting, having previously pumped up air.
    • A cut is a more serious problem than a puncture. The size of the damage is larger, the air flows out faster and the wheel deflates almost instantly. In this case, both the main part of the tire and the side part can be damaged. The side part is thinner and easy to cut. Particularly dangerous in this regard is careless driving along the roadsides, near the curbs, in a rut with sharp edges. The tire after a cut is practically not recoverable, it only needs to be replaced with another one.
    • Malfunction of the valve (spool) - this also occurs. You can simply tighten it with a key, otherwise you will have to change the part.
    • The source of air leakage from the wheel is the nipple - it is treated by simple tightening.

    Potholes or bumps in the road can be a serious problem. Hitting such an obstacle at high speed can lead to deformation of the car disk, subsequently to damage to the rubber. Very serious damage, which is impossible to fix on your own, without the use of special equipment, you need to go to a tire service.

    Use of used car tires - follow manufacturer's specified service life. Otherwise, the wheel may deflate due to high wear. There is a risk of explosion directly during operation.

    Problems exist with tubeless tires - the fitting sometimes does not fit well on the disc, air leaks occur.

    The main causes that lead to damage to car tires and air leakage are indicated. Whether it is possible to drive on a flat tire is determined by the driver himself, taking into account his experience and capabilities.

    Run-flat hazard

    Driving with a flat tire is not recommended. Driving a car is significantly more difficult, there is a risk of getting into an accident, creating a threat to other road users.

    Among the main problems that driving with low tire pressure can lead to are:

  • the problem described earlier becomes more pronounced with increasing speed, the car becomes almost uncontrollable;
  • increased fuel consumption - an inevitable companion of driving with a flat tire;
  • a completely flat tire is at risk of sidewall damage, cuts, which can make it completely unusable;
  • due to increasing pressure on the disc, there is a risk of rubber damage;
  • prolonged driving on a flat tire leads to disassembly of car tires, subsequently to damage to the disc;
  • sharp maneuvers are difficult, this is one of the factors of the accident.

A flat tire is a serious hazard. Each driver must understand this and take all necessary measures to eliminate the problem. In no case should a puncture be ignored, at high speed the situation can completely get out of control. The ideal would be to replace the wheel with a spare, repair at the nearest tire shop.

A car tire is a complex system. Consists of different elements. Manufacturers use special technologies and materials to provide the declared driving characteristics of the car. The special pattern on the main part of the tire has its own functionality, and does not serve solely for beauty. Any deviation from the norm leads to a decrease in the functionality of the tire, respectively, the car loses its qualities. Its use becomes unsafe until the problem is solved.

How much and how to drive with low pressure

It is worth noting that under no circumstances should you drive with a completely flat tire. The situation can get out of control of the driver at any time, the tire will fly off the disk, he will receive damage that will lead to new problems. It's best to call a tow truck, no matter the cost.

An exception to the rule may be a tire that still has some air left in it. You can try to get to a service station or tire fitting. You can also try to inflate the tire to give yourself more time.

Low pressure driving is possible subject to the following rules:

  • minimum driving speed;
  • the movement takes place without interfering with other road users;
  • sharp maneuvers on the road are not allowed;
  • one should be attentive to pits, irregularities;
  • it is necessary to periodically monitor the condition of the wheel, stop and check the tire.

The average distance allowed for driving with a half-flat tire is 10 kilometers. This is only allowed if the above rules are observed.

Consequences

If the problem of low tire pressure, puncture or other damage is not addressed in a timely manner, it leads to negative consequences. The following systems may experience problems:

  • brakes - work efficiency is significantly reduced, which is especially pronounced during sudden braking;
  • steering system - sharp maneuvers are difficult, any turn may be accompanied by a skid of the car, it becomes impossible to control the car;
  • wear of steering system elements;
  • punctured tires begin to overheat, which negatively affects their service life;
  • increased fuel consumption - this is due to an increased rolling resistance parameter of a flat tire;
  • Vehicle dynamics are reduced.

A vehicle with flat tires is a danger to other road users and its driving characteristics are affected.

It must be understood that movement with insufficient pressure leads to deformation of the rubber. You run the risk of completely damaging the tire, subsequently replacing it with a new one. Therefore, the decision to drive on half-flat tires must be made carefully, carefully evaluate all the consequences and alternatives.
