The Donut Spare Tire
The type of spare tire you have can make difference to the speed you can travel at as well as how far you can go. There was a time when cars all came equipped with a full-size spare. These tires are heavier and also require more storage space.
If this kind of full-size tire is your spare, you will be able to travel at your usual speed and go as far as you need to go as they are much the same as all the other tires you have on your vehicle.
Donuts are lighter, smaller, and with less tread

Going any faster could well cause some damage and then you will be in a serious pickle with no spare tire to rely on.
Donut tires are smaller than your regular tire which means that they are not built to put up with what your regular tires contend with.

One emergency on top of another
Unfortunately, with a donut spare tire, these tires are not designed to cope with your regular driving requirements. How fast can you drive on a spare tire will always give you the answer ‘not very fast’.
The reason for this is that with a spare tire you would not be able to brake- or handle your car as you normally would, and traveling at a high speed can possibly see you in grave danger of not being able to brake in time and rolling your car, and then you have a whole new emergency on your hands added to the emergency you had at home and which you now cannot attend to.
