When you are driving on the road, you must be prepared for emergencies. One of the things that can happen to you while you drive is a flat tire. If you have a spare tire, then you should be able to get back on the road.
A compact temporary tire is lightweight and does not take up as much space as a full-size spare tire. This kind of tire should only be used in emergency situations. You should drive straight to a dealership or mechanic to get the tire replaced with a compact temporary tire.
