How Long Can You Drive on a Spare Tire? The Answer Might Surprise You

A flat tire can be a dangerous and frustrating experience for any driver. After all, nobody wants to be stranded on the side of the road waiting for help. Fortunately, most cars come equipped with a spare tire to help you get back on the road in no time. Keeping an emergency spare tire and a tire changing kit in your vehicle at all times is the best way to ensure that you’re ready when disaster strikes. However, it’s important to understand that a spare tire is not intended for long-term use and has its own limitations. Here’s what you need to know about how long you can drive on a spare tire.

What Is a Spare Tire?

An emergency spare tire, also known as a “donut” tire, is a temporary tire designed to get you to a repair shop or home. Because donut tires are smaller and lighter than regular tires, they have a lower speed rating and load capacity. Most spare tires are designed to be used for up to 50 miles at speeds up to 50 mph. It’s important not to go past these perimeters when driving on a replacement tire as doing so could cause damage or a blowout.

How Long Can You Drive on a Spare Tire?

The answer to this question depends on several factors, including the type of replacement tire you have, your driving habits, and the condition of your spare tire. In general, you should not drive on a spare or donut tire for longer than it takes to get to a repair shop or home. Driving on a spare tire for an extended period can be dangerous and can cause additional damage to your vehicle. Further, don’t drive faster than 50 mph on a spare or donut tire, even if you’re on a highway. Emergency replacement tires are less durable than regular ones, so they are not able to handle excessive pressure.

Factors That Affect the Life of a Spare Tire

The life of a spare tire can be affected by several factors such as the type of spare you have, your driving habits, and what condition the tire’s in. 

Type

A full-size spare tire, which is the same size and type as your regular tires, can be driven on for longer periods of time than a spare tire. Donut tires are smaller and more lightweight and thus cannot handle the same load capacity or speeds as regular tires.

Driving Habits

Your driving habits can also affect the life of your spare tire. Driving at high speeds or on rough terrain can cause additional wear and tear on your tire and decrease its lifespan. Your spare should come with information about the maximum speed and mileage it can handle. Whenever you are driving on a spare, always drive cautiously and remain alert.

Condition

The condition of your spare tire can also impact its lifespan. If your spare is old, has been stored improperly, or has been damaged in any way, it may not be safe to drive on for even a short distance. Make sure to follow all storage and maintenance instructions for your spare tire to ensure its longevity.

What Should You Do When You Have a Flat Tire?

If you have a flat tire, the first thing you should do is safely pull over to the side of the road. Make sure that you are in an area where you can get out and move about safely. Before you exit your vehicle, turn on your hazard lights or use a reflective triangle or other warning device to alert other drivers to your presence. Go ahead and change the flat if you have a spare tire and a tire-changing kit in your car. If you do not have a spare tire or the necessary tools to install it, try to get another driver to pull over and assist, call for assistance, or walk to the nearest gas station.

How To Change a Tire

Most cars come equipped with a tire-changing kit. These kits typically include a wrench, a car jack, and a donut tire. To change your tire, first, loosen the bolts on the rim of the flat tire using the wrench, but don’t remove them completely. Next, use the car jack to slowly raise the flat tire about 2 inches off the ground. Finish removing the bolts from the rim and slowly lift the tire off of the axle. Place the spare tire onto the axle and screw in the bolts until they are secure. Slowly lower the car back to the ground using the car jack and then tighten the bolts with the wrench. Once you have successfully replaced your flat with the spare tire, drive to an auto shop or home.

Conclusion

A spare tire is a temporary solution to get you to a repair shop or home, and should not be driven on for an extended period of time. The lifespan of a spare tire depends on several factors, including its type, your driving habits, and the tire’s condition. If you have a flat tire, make sure to switch it out with a spare as soon as possible and have the flat tire repaired or replaced by a professional. Always drive with caution and keep up with your tire maintenance to ensure your safety on the road.
