The right spare tire can save you in a time of roadside crisis. Some car dealers sell a spare tire with a vehicle. Typically, these are donut tires, which are smaller and more compact. These types of tires can fit in your trunk and cost much less compared to a full-size or manufacturer-exact spare tire.Full-size spare tires have advantages as well. These are long-term tires that you can use to replace a flat tire and keep driving as normal over long distances. While donut tires are more for emergency situations, full-size spare tires are almost a match to your other tires and good for a more permanent solution after a flat.Whether you choose a compact or spare tire, you should be weary of used tires being sold as spare tires. You can always check the tread and look for the letter "T" on a tire to check the quality.
