Automotive batteries and tires have their own warranties. For example, if you have trouble with a specific brand of tire you should be able to have any tire dealer that sells that brand warranty it. Most tires and batteries have pro-rated warranties. Pro-rated means you will have to pay for part of the replacement cost, depending on how old or worn the component is that you are trying to get covered. Some tire and battery manufacturers have a full replacement period that lasts for a designated time.
