<human>:  I just changed my tire to my donut tire. How far can I drive on the freeway?
<bot>: You only have one spare tire, so you need to be extra cautious about getting your tire fixed. You should only drive a very short distance with the donut tire, and should definitely have the tire repaired as soon as possible. As a safety precaution you should use the lowest gear possible and drive no faster than 55 miles per hour, and never drive in bad weather conditions.
