Donut spare tires are not made for extended service. They have little tread to speak of, the carcass or body of the tire is not reinforced, and there is no belting to protect it from punctures and road imperfections. The tire is designed simply to get you to a repair facility.

Considering this, how do you fix a spare tire?
How to Change Tires
- Find a Safe Location. As soon as you realize you have a flat tire, do not abruptly brake or turn.
- Turn on Your Hazard Lights.
- Apply the Parking Brake.
- Apply Wheel Wedges.
- Remove the Hubcap or Wheel Cover.
- Loosen the lug nuts.
- Place the Jack Under the Vehicle.
- Raise the Vehicle With the Jack.
Subsequently, question is, can you reuse a donut? You absolutely can use it again. The places that change tires try to discourage people from using fix-a-flat because it makes a mess when they go to remove a tire, but it doesn't take away from the integrity of the tire. That being said, it's probably a good call to keep another can of fix-a-flat in the trunk.
Similarly, it is asked, how long can you drive on a donut spare tire?
70 miles
How often should you replace your spare tire?
Full-sized spare tires: Should be replaced when the tread is worn or the tire is ten years of age or older according to the sidewall date.
