Important Things You Should Know About Driving with Spare Tires

Not all spare tires are the same, you know. It is important that you know the type of spare tire you have in your car. Some spare tires are large and some are small. These smaller spare tires are called doughnuts. You should not drive these over long distances; you should just use them to get to a vulcanizer where your actual tire can be fixed.

In other cases, the spare tire is the same size as the normal tires of the car. You can make use of it the same way as you would if you were using the actual tire, no restrictions!

If you are using a doughnut, you should know that you must not drive more than 60 – 80 km/h. You should also avoid driving on a spare tire on the highway. It is very risky.

If you have an actual tire that you use as your spare tire, you can drive at any speed limit (remain in the legal range though) with it.

A type of spare tire, known as a doughnut, is not supposed to be used over long distances. Do not overwork the tire so accidents do not occur.

It is advised to stay within 60 – 80 km when driving on a spare tire. Some spare tires can actually go further distances. It all depends on the model and type of the tire.

As you know by now, spare tires are meant to be used in times of emergency. The normal air pressure for a spare tire is 60 PSI. I know you will be wondering why it is so high. The thing is that spare tires lose air pressure over time. Why?

You do not use them frequently as other tires so it advised you put more air pressure into them. If you do not put enough air pressure into your spare tire, you might be surprised one day when you see that the spare tire cannot be used because of low pressure.

Final Thoughts

Since spare tires are not to be used as regular flat tires, you need to ensure that you do not drive so fast on them. Maintain the limit and do not drive for a long distance on spare tires also. Be safe.
