A Bridgestone brand winter or "temporary use" spare tire will be replaced with an equivalent new tire for a pro-rated purchase price if the tire becomes unusable for any reason within the manufacturer’s control under the following conditions:

• There is no free replacement period.
• Coverage extends up to 5 years from the date of purchase—proof of purchase date required. Without proof of purchase date, then 6 years from the date of tire manufacture. During this period, the tire will be replaced for a pro-rated amount. To determine the replacement price, the percent of used treadwear is multiplied by DEALER’S then current selling price for the replacement tire(s). The appropriate taxes, mounting, balancing, disposal fees, and other service charges may be added to the replacement price.
• The tire must not be worn to 2/32 inch (1.6 mm) or less remaining original tread depth (i.e. worn down to the top of the built-in indicators in the tread grooves).
• Exclusions apply, as identified in the section “What This Limited Warranty Does Not Cover."
