When you're choosing a spare tire, there are a number of things to look for. You will need to check to see if the inflation is proper. The space saver spare that is standard now in most vehicles is fine. Usually, the wheel wells in these cars today are too small to put in a full size spare. Also the space-saver tire is good for about 5,000 miles without any problems. The idea of a spare tire is to get you into the service station to get your original tire repaired. So keep that tire inflated properly. Space saver is nice and easy for a customer to handle. They're about half the weight of a regular full-size tire. But as far as your maintenance is keeping those tires rotated, balanced, and the space-saver or a full-size spare aired out properly.
