As a rule of thumb, tires are usually meant to last about 50,000 – 60,000 miles per every change, but it really depends on how much you're driving and where you're driving to. Unfortunately, there is really no way of telling how long a tire actually lasts. Your tire life is dependent on the climate in which the tires are mostly driven in, your personal driving habits, and how long you've had them. From the date of manufacture, it's important to have your tires at least checked after five years. If you have had no issues and you are experiencing no slip while turning or coming to a complete stop, then you should be fine, but again, they need to be inspected.
Your spare tire should not be used every day! If you think you can just replace one of your old tires this way, unfortunately, this is not the case.
